Hi Herb; I've seen those, they're 3-4 hundred dollars. It would be the perfect thing, I'm going to try to get off cheaper if I can though. My entire heating setup, accurate to 1/2 degree will run about 50 dollars. ;-) I'll have to see if one of the local stores has the aquarium chillers, maybe I can steal an idea or two.
