I use an adjustable desk with an electric motor. I switch between sitting and standing 4-5 times a day. That's probably the best for you, I like it a lot. I got the cheapest model at a company call the human solution, the 445 and it's great. They start under 800. http://www.thehumansolution.com/elheadde.html[^] There was also a place called nerddesk, that had some lower priced desks, but they didn't have a center cut.
