Has anyone made their own height adjustable desk? I'm interested in making a computer desk that can easily be adjusted for either standing or sitting.
The lift mechanism could be electric or mechanical, as long as it is not too hard or time-consuming to adjust.
(There are commercial options around, but they start at $700 for the cheapest of the cheap. I'm sure I could make something myself for less that would better suit my needs.)
Update: Just to answer some of the questions in the comments. The desk would be supporting two 22" LCD monitors, a laptop, paper and anything I leave lying around the house long enough for her to throw on my desk. :-)
I do have access to some welding expertise.
Also, I live in Australia so importing from many of the places suggested would be impractical.
