The best ones for a tank setup are the proporational. The two most common brands out there are the Herpstat and the Helix. They both run about $120-$130 or so. You can also get a non-proporational one for around $60-$75 such as a Johnson or Ranco. Either way, they're much better than a dimmer especially if you have the tank in a room that might fluctuate more than 5-10 degrees throughout the day. You can get more info at Reptilebasics.com and spyderrobotics.com for the Herpstat.Originally Posted by synister370
