Speaking as the designer of the A2320 Display Enhancer I can tell you
several benifits the A2320 has over the MicroWay product over and above
the price.  First, the A2320 has FULL overscan support for BOTH PAL and
NTSC displays (768x489 for NTSC and 768x576 for PAL), then there is the
automatic switching of de-interlacing of interlaced images to
when in interlace mode to scan-doubling of non-interlaced images when in
non-interlace modes that results in NO video artifacts (ghosting or
smearing) which is a real plus for scrolling display, games, etc.  There
is also automatic genlock support (both for NTSC and PAL genlocks) such
that if an external genlock is connected to the Amiga (and is meets our
guidelines for how a genlock should interface with the Amiga) the A2320
will de-interlace the Amiga's reference RGB output to provide a flicker
free display.  The A2320 also works with the new ECS graphics modes such
as the `Productivity' mode by automatically sensing this mode and
bypassing the Amiga generated 31.5Khz video to the multiscan monitor
connected to the A2320's video output connector.  This allows the A2320
to work with this mode without moving cables or removing the video card
as you might have to do with the MicroWay product.  The card also has a
user controlled bypass switch that allows you to manually do the
bypassing of the video data for the ECS `Superhires' modes or any other
graphics modes that you desire to bypass to the monitor.  This also
allows you to do a before and after enhancing effect so you can see what
a difference the A2320 can make on your graphics screens!  The A2320
also can automatically switch between PAL and NTSC video modes so that
the card can more fully support AmigaDOS 2.0.  The lower cost is due to
the very high intergration of the AMBER gate array and the special video
memorys that only recently have become available. 
I hope that this answers your questions, and sorry for the sloppy
typing!
