I would like to second Mr. Parker's suggestions.  NeXT currently does
not offer a expandable machine that has inexpensive color support.

If you want color on a NeXT, you either have to get a color slab (NeXTstation)
or a cube with a NeXTdimension.  The slabs have no slots for expandibility
(at the very least, this makes it very difficult to ever upgrade to the
next latest and greatest CPU (68050 or multi-processor support etc.
whatever it might be).  And the NeXTdimension appears too expensive for
people who aren't doing professional graphics work or scientific
visualization or who don't have a lot of money burning a hole in
the pocket.

Why not offer a motherboard for the cube that has the 16-bit color
support builtin?  I would pay $375 dollars for such support even
if I didn't plan on going with color right away.  I may be wrong,
but I can see many others doing the same thing.  With NeXT's
sophisticated factory, it shouldn't be any problem to add support
for one more type of motherboard, should it?

Furthermore, why not offer a slab that contains support for grayscale
and color?  (A multi-headed slab would then be a possibility).

These sound like good ideas to me.

  I was worried about the expandibility of the NeXTcolor station
myself when I began looking at NeXTs.  I finaly bought a cube
because a) I got in under the wire at the buisnessland fire sale (
thank god i don't have to deal with them anymore!) and 2) It was
cheaper than the color station I was looking at.
  At any rate i asked the local NeXT rep about the expandibility of
the NeXT stations because I didn't want to get left behind when the
new wave of cpu's came out, and he told me thet he believes when
that happens you will be able to do a motherboard swap for about
$1000 just like on the cube.  It seems to me that one could easily
cough up another $500 or whatever, to get color thrown in with that.
  I know the color may be more than this, all I can say is start
saving now!  Either way it's not cheap.  Someone should also call
NeXt up and confirm that stations will be upgradeable, but I have a
cube, so I don't have to call 8-).
