If it were a couple extra dollars, I'm sure no one would go for the cheaper On/Off thermostats, though for many people $100 price difference is not "a couple extra dollars". Personally I don't know which I will put in my rack, but I can certainly understand those who have other things to spend money on than a 130 thermostat, especially since many people have kept and bred reptiles successfully with the $30 thermostats.
