I know a ton of people choose to mod them and add a fan, which I am doing after last egg hatches in a day or so, but what about a new thermostat? Home depot sells a nice simple digital thermostat from 19.99. I bought this for my house and its accurate to within 1` + or -. I'm not an electrican so I am wondering if it could be possible and how affective it could be? It also has settings for a fan option and that can be wired/controlled seperatly from the heating element so a fan kit could be added and easily controlled off/on without using and additional power source?
