Space heaters, especially for northern folk. My whole house remains a constant 58F in the winter months but the frog room is kept at 71 with a 20 dollar space heater. I have only used one model but it has worked great so far. It shaves a lot of money off the heating bill each month.
The only bad thing is that you have to manually turn it on/off, it doesn't adjust based on the temp in the room. There is an "eco setting" where it automatically shuts off after 4 hours, otherwise you have to either put it on a timer or adjust it manually.
I got mine at target, not sure if they still carry it though.
