I have a Dave Korrey
3 window body and for the money I believe he produces the best around. Mine came with doors and truck hung, electric window units, and bear claw latches installed. The fiberglass is thick and although I haven't started the body work as yet it looks pretty straight.
I will say one thing. I've had mine for about 10 years (it takes me a long time to collect the parts for a project) and during that time the price has almost doubled but even at today's price its a darn good deal.
