If you don't mind working on your bike outside, you make a bike stand cheap. Find a nice spot under a shade tree and sink a 4X4 post into the ground. Add some water while tamping the dirt around in the hole to make a wobble-free installment. Screw a $6 bike storage rack to the post and presto – a great place to wash and wrench your bike. Unlike a real bike stand, there's no clamp to deal with, so it's quick to use. If you need, spread a large square of outdoor carpet or something similar on the ground underneath to catch parts and prevent making a mud pie.
