What is the best reostat to use for temp control on a UTH? I have one that I got from Wal-Mart, and it does not seem to be keeping the temperature. In the am it will read 92, when I get home my temp will be 101-102, this is on the UTH and not the belly heat temp.

It is just a little bit annoying to see it doing this. I really dont want to be out another 50 bucks on a thermostat.

So which one should I use?
