I saw some pictures of work that a guy does and his work is nothing short of spectacular. I don't know much he charges, but maybe someone else here does. He does a lot of work for folks on the AV 123 board and goes by something like "Brucer" if I recall. Anyone know who I'm talking about?? I tried to log onto the AV web sight and it appears to be having troubles.

At any rate, custom is the way to go as you can pick your species of wood, size, shape, finish. You could always make some phone calls to some cabinet makers in your area. When you do, feel them out and ask if they make, or buy the doors. If they buy the doors, they've gone "production" and away from "custom" as the doors take real craftsmanship and time, whereas the cases just take a good table saw.
