I bought the cheapest one eBay had, something like 24.99 from Discount Tommy or something like that. It has scissor legs, a bb holder, and a DT holder with clamp. It basically is a POS, but I only intended for it to be used a couple of times, only wanted a bike or two...
I'm still using it, but for wrapping bars and running cables, I use a rear wheel stand from PBK for $10. For building, I have an old MagnaDyne trainer on an old kid's school desk. Height is right, I can run a bike through the gears, work on bb and most of the stuff I drop hits the desk.....
I really need a good stand and a magnetic mat.
