I'll mail you my old one if you'd like (~5 years old). I had installed it in my previous house, though had to remove it and reinstall the original when I moved out (it doesn't support a gas heater function (I didn't use the heater for the three years I lived there)). My daughter now uses it as a toy, but as far as I can tell it still works.
ETA: Needless to say, if your setup includes a gas heater, this wouldn't work for you. Keep this in mind when shopping.
