You should specify your needs. For a (relatively) warm climate of AZ, where you don't need a lot of heat, and only need it from sunset to bedtime and from wake-up to sunrise, I don't think it matters. You only need to raise a temperature by 10-15 degrees, for a few hours. You don't need 77F all the night when you sleep, get a nice warm duvet instead. I wouldn't leave these small heaters on overnight, either.
Thermostat you probably won't find on these. At best, there will be 3-position regulator for heat output, high-medium-low.
I installed catalytic heater Olympian Wave 6 on the wall, and so far happy with it. 6000 BTU is probably overkill in this climate, but smaller 3000 bTU might not be enough on some winter days. Same 3-position switch, radiant heat (no flame). Less propane (a lot less) than blue flame heaters, less oxygen consumed and less CO emitted. They can be used as "portable", with optional legs, if you prefer.
Edit-PS:
I don't like the term "vent-free" used in the article above. It is misleading. Makes you think that you don't need venting. It's better to have a vented heater, but they are rare or bulky. I tried to get a vented catalytic RV heater from the only company that makes them, but they were having some production problems. So I opted for non-vented heater. You do need to leave your windows or roof vents open a crack, with any heater from 3000 BTU and up. They all consume oxygen and emit CO2 and CO (and water vapor of course). Blue flame are worse than catalytic, in this respect.
