Standing desk using IKEA parts. This is the configuration (maybe with a few tweaks and some nonskids added) that I've decided on and works for my height (5'9.5"). I still need to attach the legs and the cable organizer tomorrow. Everything is just sitting on top of each other now.
2x Linnmon table tops @ $16ea.
2x Finnvard trestles @ $30ea.
2x Capita 6" set of (4) legs @14ea.
1x Signum cable organizer @ $10.
Total: $130. And it looks decent, too. Also, the Finnvard trestles can adjust down for a shorter height.
It just occurred to me that I'll have a perfect coffee table in case I ever use the trestles in something else.
