My suggestion:
1. make a metal box
2. wrap the box with heater wire or tape
3. place Styrofoam around the box, keep it away from the heater tape/wire
with spacers so you don't melt it
4. buy a temperature controller and a thermocouple - such as Omega 6100 http://www.omega.com/ppt/pptsc.asp?ref=6100_CONTROLLER
5. maintain the temperature above room temperature so that you only need to
heat it

Can I tap the collective wisdom of the list?
We're building a radio telescope, and the front-end electronics at the dish
need to be in a stable environment. We're looking for a weather-tight box
about the size of a picnic cooler which has temperature controls (both
heating and cooling) to hold the electronics within a 10 degree range. Any
pointers? Our physical facilities folks have had no luck.
