I bought a 4WD Hardware steel frame. It seems to be of very high quality, oem thickness of steel, arrived with no dents/bends, and it comes in a nice black fatory "e-coat" type finish. I scuffed it with a scotch brite pad, wiped it down with some wax/silicone remover and painted it. I've been told to stay away from 'glass w/s frames 'cause they lack ANY sort of strength...and with the windshiels itself being perfectly flat, it has no strength either. I would only consider a 'glass frame if you are going to run a hardtop all the time (to keep it in place). Otherwise, go with steel. My original lasted almost 20 years, and if I have to spend another $140 on a new one in 20 years, that's fine with me.
