If you can afford the $80, go with a Johnson. They are the most reliable and stable of all the stats.

The ZooMed stat is a great 'for now' stat, that once you have dialed in (which can take some time) it stays where it should be. I've only ever had 3 degree flux max with them.

Here is the scoop on probes and tstats: The ONLY stats that can have more than one temperature programmed and controlled - ie that have more than one probe - are the Herpstat II and Pro. That is it.
When you have two enclosures and want both warm sides controlled, a ZooMed stat will do the trick. It has two plugs, but you can add extenders as long as you do NOT come close to the 500 watt limit. Since UTHs typically run at 8-10 watts each, you won't have to worry about that.
When you have TWO UTHs on each enclosure, as I do, and need to control both the warm AND cool sides, then you need two tstats or the Herpstat II.

And yes, it's best just to tape the thermostat probe to the bottom of the pad. Works just as well then, since it's not the stat number you read but the thermometer number.
