I've got an older (and larger) version of that desk and really like it. I've set it up in standing mode before, but didn't really stick with it.

It's worth checking Craigslist in your area too, there's usually people selling these desks pretty cheap. At least that's been my experience; got mine used for $70.

EDIT: The Jerker (http://i.imgur.com/TyieC.jpg) is what I actually have (thanks chaostheory).

i've also been using a jerker for over 10 years now, with the last few in stand-up mode:

they really are great desks and are very configurable.
