Roofarmer. I take your point on cheap'n'crappy . but as bladeracer said, as long as the basic design is good theres no problem.
I have 2 pair in the shed. heavy duty ratchet type that were about $90 and a lighter steel tube and pin type that were about $45 on spesh lol. obviously the HD ratchet stands are rated higher, but both are good IMO.
