Well, I haven't actually *SEEN* one running BUT, I can tell you a few things:

Using a "standard" VGA monitor is not a good idea because it is a
single-frequency  monitor, which means you cannot use PAL mode (with the
one meg Agnus).   If you get a "Super" VGA (SVGA) monitor, you will be
able to use PAL (since SVGA monitors will adjust to different frequency
within a limited range).  Also, most VGA and SVGA do not seem to have
horizontal size adjust, and from what I have been told about ICD's FFV,
and the same is true for C='s A2320 (which is what I have), you really
need this feature.  What you get on a (S)VGA monitor is FULL overscan,
with about a 1/2" strip down the left & right sides of the image, which
really is a waste of monitor space.  Its not a big deal, but it is
annoying.  I compensate for this by using a 700-pixel wide WB screen
:^).  Another thing is that you will not be able to use some of the new
ECS modes (specificly Super-Hi-res) on a VGA monitor.  My A2320 docs say
to put the card into "bypass" mode to use Super Hires.  And since this
is a 15KHz signal, my monitor doesn't take too kindly to that.

My recommendation:  Go with a SVGA monitor if you can't afford a
multi-sync.  (that's what I did).  If you can find a SVGA with
Horizontal size adjust, all the better.  Word of warning:  Lo-res (i.e.
non-interlaced) looks really lousy since you can see every pixel in
perfect clarity... there are no visible scan lines to hide the lack of
resolution (like on a 108[0|4|4S|4D|4DS] monitor).  Oh well, you will
have to suffer with a Hires workbench screen ;^).

As I said before, I haven't seen FFV in action, but I have seen the DOCs
for it, and have been told about it by a friend who used it.  I have
also used C='s A2320, and these are the conclusions I came to. I still
wish I spent the extra $250 for that NEC 3-D monitor!  But my SVGA is
more than adequate.
