I bought the Pro Exotics PE-2 Infrared Laser Temp Gun and have been using it for a few days now. I really like it. It's very easy to use...you just point it at the spot where you want to get the temp reading, click a button, and it gives you the temp. I had heard that once you started using a temp gun, you could see how off your temps were before using digital thermometers. I definitely see a big difference in the readings. Plus, you can use the gun to check basking spot temps...warm side, cool side...you can get a temp reading for any area you choose. I find the readings are pretty close to my thermostat settings...only off by about one degree. I found it on ebay for $34. Definitely worth the money.
