From what I've seen so far, AP has the best prices for PVC enclosures, though the wait time is lengthy. I think the T8 enclosures are still on sale (150 each), though with black friday coming up, there may be more sales popping up. Then you'll want to factor in the heat source. Radiant heat panels are a godsend (proheat is the best out there), and if you have them shipped to AP they do beautifully seamless installations. That's my sales pitch they really are fantastic though, I have 6 of them.
