good incubators

I am eventually going to breed my balls but I want a good incubator. I have seen the ones at J.W. Exotics and I like them but I want something that is not going to make my meter run 100 to nothing. I am interested in a low wattage and good incubator. If I can get any more information on J W Exotics's incubators I might buy from him.

Manufactored incubators are great, but an old fridge and the DIY forum will do the same thing a lot cheaper.

Damon Salceies has an awesome design you may like to check out if you want to put one together yourself. http://www.kingsnake.com/salceies/Incubator.htm
