Here are summaries of the reponses I got.   Thanks.

Anyway, the Amiga is the way.  There is a real cheap and very high quality
color digitizer that uses a black and white (cheap) surveillance camera
and three shots through an RGB color wheel.  It gives great results if you
can get the subject to stand still.  Digitizing color photos or
magazine stuff works great.

The product is called Digi-View, and consists of a tiny little A-D that
hangs off the parallel port, a cheap camera, and a copy stand that
you hook the color wheel and the camera to.

The company is NewTek, Inc, in Topka Kansas.

An Amiga with one of these is PROBABLY cheaper than the equivalent
add of for a PC, even if you have the PC.

The Amiga printer drivers allow for device-independent color output
to a variety of cheap and expensive printers, and will fake it on
a black and white printer with your choice of thresholds, dither patterns,
etc.

The paint programs can work with these pictures in a special HAM mode,
with 4096 colors possible.

You can't beat it on a budget, no way.

If you don't need a frame grabber, ComputerEyes from Digital Vision is a good
choice.  Digitizes at 320x200, takes 6-12 seconds to scan an image, $250.  New
color version is somewhere around $400.  I picked up a used b/w video camera, so
my total was under $400.
The software now allows saving in various formats so you can bring the image
into paint programs such a PC Paint+, PC Paintbrush and Dr. Halo.

   Truevision Inc., has the ICB card which offers 256 x 256 x 16 bits per
   pixel (32,768 colors at one time -- 5 bits red, 5 bits green and 5 bits
   blue with the 16th bit used to specify if an individual pixel is live
   video or stored frame buffer graphics).  

   The board will handle real-time frame grabbing (30 frames per second) via
   a NTSC color camera input (you supply the camera).  It sends out NTSC and
   RGB signals to the monitor (which you also supply).  You can specify on
   a PIXEL by PIXEL basis whether an individual pixel is seeing live video,
   grabbing live video, or seeing stored graphics.  This allows you to combine
   live video with stored graphics at the same time.  

   For more information, contact:   Truevision Inc.,
				    7351 Shadeland Station
				    Indianapolis, Indiana  46256

				    (don't call me.. ask for pricing or
				    closest dealer information - I'm just
				    a lowly hack)

    If you need more resolution (color or image) we also offer the TARGA and
    VISTA boards which support 512 x 512 and up to 1024 x 768 x 32 (as in the
    VISTA series).. we also support the VISTA for the MAC II... but these are
    much higher costing boards.

2 options come to mind.

A) AT&T has (had?) something called Image Capture Board that does 
what you want, for I think around $500. It was introduced at the
same time as the Targa stuff (from Truevision group). Haven't heard
anything about them lately - I (and apparently everyone else) went
for the higher resolution Targas.

B) I've seen ads (e.g. in BYTE) for capture boards that work with VGA
cards.

Try contacting Xybion Electronics Corporation in San Diego, CA.  Their
telephone number is 619/566-7850.

The make cameras and frame grabbers, and sell image processing software.
I believe all of their stuff runs on IBM PC compatible hardware.

Try Imaging Technology, Inc (ITI) - They have cards for the IBM-PC/AT

Our company has such a product.  Call (301) 495-3305 and ask for information
on "HALOVision".  Contact me by e-mail if you have any questions.  (Remember
I'm an Engineer and am no good for prices/quotes, but I think it's 
good value for money)

Digitizer:

True color or color mapped? Truevision's Targa 16 is 512x400x16
truecolor. Everex has a functionally equivalent board for a whole lot
less money, I don't know the model but I could find it if you need it.
What are you capturing? If it is live video you need a fast digitizer
like this. 8 bits probably means color mapped which usually means
capture one plane at a time (R,G,B) and then build the image, so the
image has to be still. (Copy stand)

Do you need one digitizing station and multiple display stations?

Display:

Why display on the system monitor? Is this a requirement? System monitors
are usually digital TTL input or monochrome, unless you are using a
multi-sync. I recommend a separate monitor for graphics and a monochrome
monitor for the system. I don't know of any frame buffers that will work
as a system video display on the PC. Life is much easier with two displays,
and no more expensive.

If you can afford a Sony CPD-1302, that's my favorite. Most versatile, too.

Hardcopy:

What resolution? What will it be used for? I can't make any
recommendations for a cheap, high quality output. They are either
awful and cheap or good and expensive. I prefer a film recorder to a
printer personally. Let me know if you find something exciting here.

Other:

Don't bother with a PC, they are TOO SLOW. Get an AT class machine.
Plan on getting an EMS memory board if you will be using a paint
system. Make sure the computer is compatible with the frame buffer.
Some clones AREN'T.

An Amiga 500 and a Digi-View digitizer+camera+stand costs less than $1000
and can produce 320 x 200 x 4096 color pictures, 320 x 400 x 4096, and
640 x 400 x 16 shades of gray.

I believe there are a couple of well-known Amiga hackers at Ferranti that
could show you the capabilities of the Amiga as a digitizer.

Colour would not be very simple (and therefore not quite inexpensive)!

If You can live with B&W, try Steve Ciarcia's ImageWise Serial Digital
Imaging System.
It is available from 
	Circuit Cellar Inc
	4 Park St.
	Suite 12
	Vernon, CT 06066

Prices: Digitizer/Transmitter	DT01 (Full Kit)	$249
	Dispay/Receiver		DR01 (Full Kit)	$249

The DT01 grabs and digitizes a standard B&W picture into 256x256 dots
with 6 bits of grey scale and transmits it over an RS232 line.
The DR01 does the reverse.
There are provisions to use a color camera, but, again, only B&W digitization.
