I don't if anyone is currently looking for an enclosure for their control panel but I found this last night on ebay and ordered one. From what I can see it should work fine. Not really a watertight NEMA box but since I'm cutting a bunch of holes in it I'm not to worried about it.
Once it arrives I'll post back if it's junk, or a good deal.
(Of course I've never built one of these so feel free to let me know if I bought a bad idea.)
