If they are the ones in Orange, CA, I have bought a bunch of stuff from them. Never sheet metal though. Their prices seem well below other suppliers (which is good) but the SOME of the employees behind the counter should be doing something else-i.e. not much help so you need to know exactly what you want.

The parts that I have purchased and installed seem to work fine.

If this is not the supplier you are talking about then------Nevermind.
