I disagree about the "you'll wish you would of gotten a herpstat or helix" they are EXTREMELY expensive and the average joe may not be able to afford that, like me
So I ordered a 26 dollar (total 33$, shipping was 7) DIGITAL thermostat that has amazing reveiws from several hundred people on multiple websites
this is the best option until you can manage to buy/save for a herpstar ect.

2nd one listed to the top
AMAZING deal, has very good reveiws from multiple websites as I said, and is digital.
absolutely amazing
