She usually answers the phone, and knows her stuff. Corky does quite a bit of their one-off fabrication.

I'm fairly confident if you can mail them your defective unit, they'll be able to make you an identical one for much less than 4k. Don't quote me, but I'd think it'd be around a grand. May be a little less.

Edit: You'll have to wait until Monday to contact them. Only Corky is there on Saturdays and he stays in the shop.
