Best bang for the buck? Well, I recently made something like this bike stand:
home made bike stand
Looks kind of like this:
Cost me $12 for the 3/4 inch pipe clamp, and less than $10 for a 3/4 inch base flange, one 3/4" x 18" long pipe, 3/4 x 12" pipe, and a 3/4 inch elbow, and maybe $1.50 in bolts and nuts to bolt it to my work bench. Unlike the one on the website above that hangs from the ceiling, mine is bolted onto my garage work bench, right next to my bench vise. you'll need a drill with a 1" hole saw or spade bit. Maybe 30 minutes to one hour of shop time drilling holes and putting it together, and viola', you have an excellent work stand for under $25. When I don't want it on my work benck, I just unscrew it from the base (which is through bolted to the bench). Works perfectly.
