You can build the exact same thing with a bar fridge! I put an ad last year on a classifed website asking for a broken fridge and I got two, one works and one doesn't for free. I used the broken one(removed compressor and controls) and put in 3 feet of 11" flexwatt, a digital thermometer and a thermostat for about $125 and it will hold 8 to 10 clutches! You can build it in just 2 hours! It will work just as good and hold alot more clutches! After looking at the inside measurements, the Reptipro can't even hold a shoe box size tub! That's they size of tub you will need to use for your egg box!
