Which thermostat

Im buying my second snake rack with 7 bins. My old thermostat company doesnt exist so Im wondering what is a good one to go with?

All depend on what you want to spend. My first choices are Herpstat or Helix, both are top of the line and more expensive. Next I would consider Johnson Control or Ranco ETC-111000. These are both good, just operate a little different than the other two I listed. And these last two make clicking sounds when they turn off and on while keeping the right temp.
Here are a couple sites for you to check out.

Hope this helps!
