One alternative is a set of ropes and pulleys w/hooks attached to the garage ceiling. Never tried it, read about it somewhere. Performance has a decent workstand that folds up for storage, although since getting it, I mostly leave mine out and use it to store my bike. I got it on sale for about $120 if memory serves.

I've read that the models with tri-pod leg set-ups are more stable than those with legs that are flat on the floor.
