hmmm, well price is not 2 much a factor, but I refuse to spend over $350 on something I may OR may NOT need. Earl I would use your suggested method, but don't want to start cutting holes in my res. My temperatures appear to be extremely variable. I feel that a chiller would be able to keep me at 68 all the time without venting the room, dumping ice in my res or some other dumbness. Thanks for u guys helps and ideas. Has anyone seen a significant jump on a power bill using a chiller? They are not technically on all the time...so cant be that much more power r ight?
