@YouInMyEye They all rust out and disintegrate, and can be rebuilt from parts. Unless you're aiming for professional grilling IMO they're functionally equivalent. The grill masters I learned from will go to the local park and use whatever's there.
@YouInMyEye Maybe try the manufacturer directly; that's worked for me. They have websites. I don't know anything about Amazon.

I guess Amazon only sells GrillMaster parts.
