So I bought the ZooMed Rheostat at petsmart to control my undertank heater--it was crap. Even on the lowest setting possible, the temp was still reading 98 F. So I returned that and ordered the ReptiTemp 500 online, I haven't received it yet.

I was in Petco this morning to get dog food and browsed their reptile section and saw they had the Zilla Temperature Controller 1000w on clearance for $4! So I bought two, figuring I could at least sell the extras on eBay or something. =D

Any way, so now I have two Zilla Temp Controllers at my house, in package, and the ReptiTemp 500 in the mail. Which is the better one? i.e. which should I keep and which should I sell on ebay? lol
