Crispi, I am this close to getting a Prime USA 1/15 HP 750 BTU chiller for my res - it's $280 delivered. Claims it will lower the temp by 10 degrees in a 80 gal tank so it should be fine for my use.

BTW, anyone that saw "John from Cincinnati" on HBO last night - that show is set in my town and the main set (the motel) is only a few blocks from me. I see them filming around town all the time and Ive watched them do a couple of scenes...
