I will be breeding my corn snakes, perhaps as early as this season, and am looking for CHEAP ideas on an incubator. I have been searching like mad and have seen various posts on coolers, old fridges and freezers, and Styrofoam crates... but has anyone ever thought to use an old microwave?

They are really well insulated, have no freon to drain, can be found really cheap at thrift stores and pawn shops, and already have a handy window for viewing. Plus, the small capacity would be great as I would only ever have at most two clutches going at any time. I have the flexwatt and could use my Ranco stat, all I would need is a fan and we have an old computer we're getting rid of soon.

So, anyone see any problems with this idea? I could probably get my hands on a small dorm fridge for @$10-30 if I had to...but there's no window.
