My current fav among commercially available thermostats is the Filtrete 3M-50 Wifi Thermostat (aka. the CT-30/CT300E Wifi). It sells for about $110 at Home Depot in the USA.

I don't have one, but were I to purchase a new thermostat, that's what I'd get.

Instead, I've decided to just make one that works how I want it to work. An Atmega328p PIC (w/Arduino bootloader), LCD screen, some buttons, a couple of relays, RTC, temperature sensor, and either ethernet or an ElectricImp for remote access and easier programming.

Yeah, I'm weird.
