For $50 I built my own desk. Not only is it perfect for my computer, but I also built in a cupboard that holds all my paper and stuff. This acts asan extra sturdy leg.
Beat me to it by a minute. Why not make your own desk, or get some help from a carpenter-friend? You must know somebody with a hammer, all you need is a basic layout and wood. Unless you want to go uber-fancy with drawers..... I hate drawers....
But yeah. I made a desk for my workstation. REALLY sturdy. No drawers, bout them seperatly.
