I am currently using the display enhancer with a "Super-VGA" monitor
(you know the 800x600 non-interlaced, and 1024x768 interlaced ones), with no
problems.  The only thing I don't like is the fact that my monitor doesn't
have a horizontal width adjustment so I have about 1/2" of black
nothingness on either side of the image.  Of course to compensate for
this I put my workbench screen into 700pixel wide overscan and it looks
really pretty.  The only problem you will encounter is if you try to use
the ECS "Super-hires" mode (1280x200/400).  The card doen't sample the
pixels fast enough to get 1280 on one scan line, so it will only sample
every second on (giving you the 640-wide resolution).  The manual says
to put the card into bypass mode for this, which of course the VGA
monitor cannot handle.  Another small complaint I have about the card is
that it makes lo-res look really crappy.  You can see each pixel with
perfect clarity (no scanlines and cheaply made monitor to hide it).  I
really cannot stand to look at a non-interlaced workbench screen anymore
(WB 2.0 looks pretty lousy in non-interlace anyway :^) ).  
The only trouble you may have with a VGA (not Super-VGA) monitor is if
you switch to PAL (w/ [Super | Fatter | Obese | Fatter | Pregnant | Huge
| really-neat-now-I-have-a-whole-meg-of-chip-RAM] Agnus), it may not
work.  I'm not sure about this but I think the frequency is a little
different for PAL, and a standard VGA monitor may not like this
(Super-VGA monitors will adjust
within a limited range... mine goes from 28-33KHz I think).
