Holy crap! $125 for a thermostat!? That was way more then I anticipated. Is that absolutely necessary? Also, could I get away with the walmart thermometer? Lastly, I am really concerned with the holes. Could you give me a ballpark estimate lol? What do you do personally? What size holes and generally how many? I don't want to skimp but there's no way I could swing a $125 thermostat. Someone pointed this out: http://lllreptile.com/store/catalog/...tat-150-watts/. Would that do the job?
