BUMP for a really great thread.

Ive been working on a similar setup, but I think im gonna switch to this. I have 2 questions for anyone thats built one, both having to do with the air supply..

1. I went around to a couple of pet stores to get a pump. All I found was battery operated pumps. Is that what you guys are using? I dont like changing (and buying lol) batteries every so often. I want a pump that I can plug in.

2. The T fitting.. I cant find one small enough. Lowes and HD carry a 1/4" nylon T, but the 1/4" hose wont fit over it. They dont sell any smaller T's, the 2 pet stores i went to dont either, they reccomended buying another pump for $12 (of course).
Should I just get the hose warm enough to stretch it over the fittings?
