Or just get a tall desk chair. They make desk chairs that are tall like bar stools for standing desks. (http://goo.gl/5zMCq) Then you can stand when you want or sit when you want. Pulling the chair up seems easier than raising/lowering a desk
it takes about 3 seconds to lower or raise my (electric) height adjustable desk. I got it for £200 off ebay. You can just about see the mechanism on this post about my workspace http://qiip.me/edlea/blogger/post/4019
