I built a DIY bike repair stand. It is made with steel pipe fastened to a plywood board for the stand and uses a pony clamp and a couple blocks of wood with notches cut out for the clamp. I can do anything with that stand, up to and including headsets. It doesn't pivot like a real repair stand, so it's not quite as versatile (and it certainly doesn't travel), but on the other hand, it is heavier and more solid and steady than most consumer repair stands. And it only cost me about $30 in material and about an hour or two of time to build. Been working for me for about three years now; I use it almost daily.
