Maybe you want to know this: I bought this Hazet 9033-5 orbital sander/polisher. I'll be short: It is great. Final polishing reduced to 1/4 of the time. Pro's: High speed, diecast housing, good grip, almost silent. Cons (for me): expensive and it takes a lot of air. It sucks my compressor (25l, 120 psi, 2 hp) empty in 1 minute. At work we have a real big compressor, so from now on I'll do the polishing over there. But otherwise I can recommend to you.
