Home Thermostat recommendation?

[Lee3]

I have a Ritetemp from Home Depot. It has worked well for 5 years. The reason I bought it is because you can adjust the "swing". This means I can tell it to go 1 degree over or under the set temp. I set the temp at 67, the heater wont come on until the temp goes below 66 and turns off just above 68. I think this saves wear and tear on the heating and cooling system as it doesn't go on and off as much. I don't notice the swing in temperature.
