[comp.sys.amiga] DiamondScan monitors

About a month ago, I asked about DiamondScan monitors and the cable, and
thanks to all who posted or emailed suggestions.  I ended up getting a
DiamondScan for $500 mail order, and picked up a cable (made by Redmond
Cable) from the Memory Location for around $25.  As previously reported,
the DiamondScan has excellent color saturation, and a pretty good dot
pitch.  It looks wonderful on top my A1000 -- I wish this had been the
monitor I got with my machine.  There have been several questions posted
on the net re:monitors which I might be able to answer:

1) Why all the fuss about multiscan monitors?

If you buy a FlickerFixer or intend to upgrade to the 1.4 chipset (I
am planning on getting a 2000 eventually), you will need a multisync
to take advantage of the new non-interlaced modes.  Might as well start
thinking about it now if you're in the market for a monitor, as I was.

Also, multiscans generally tend to be of significantly higher quality than
the 1080 or 1084.  I am very happy with mine, even though I still use a
non-interlaced Workbench screen.  The black on this thing is a *real*
black (at normal brightness levels), which persuaded me to switch to a
light-char on black-background color scheme that looks quite nice.  With
my 1080, I couldn't quite tolerate this (and in fact used black chars on
a light screen).

2) There were some questions about the inputs on a DiamondScan.  It has
three inputs: Standard composite video, RGB analog, and RGB TTL (IBM
standard).  The Amiga doesn't like one of the RGB analog signals
which necessitates a special cable (available commercially, see above,
also a schematic was posted to the net).  The manual even claims some way
to superimpose an Analog RGB image onto a Composite video one, but it
looks like it might be messy (cut <-> cable <-> splice).
