I happen to own a DPM Super Cub (great airplane), I'm very pleased with it, quality throughout! When it first arrived this past summer, one of the wingtips was damaged (very minimal though), I called Dave and he offered to replace the wing, I really didn't want to wait around for something that I could easily fix, so I was interested in the instrument panel for the Cub and he sent it to me for free. So no complaints here and I haven't had any other problems. Having said that however, I think customer service goes hand in hand with a good product, and I agree with "Desertpig", paying someone to man a phone would be a lot cheaper than losing customers.
