Marc,
  I've found that most monitors will easily do 1280x1024 @ 96Hz, which while
not as nice as 120Hz, is far less demanding of both the monitor and the
glasses. Some of the stereo glasses we have (particularly older CrystalEyes
glasses) didn't perform very well at 120 Hz, and were much better at 112 Hz,
independent of what monitor was used. We've been using 108Hz and 112Hz on
most of our machines for that reason. I would think that 108Hz would be
achievable on many CRT monitors. I just did a quick scan of input
bandwidth (aka dot rate, pixel clock) on some relatively inexpensive monitors,
and it appears that many can go up to 350MHz or more
(width * height * refresh rate), which should be
easily high enough for most stereo modes. Any monitor that can hit
2048x1536 @ 80Hz ought to work fine for 1280x1024 or better @ 112Hz or so.

Here are some examples:

NEC (marginal on peak refresh rate...)

I'm sure there are many others out there, you just have to dig around a bit.
