Uth termostats

[OhhWatALoser]

What's a good reliable brand of thermostat to use with an uth ?

Herpstat, helix

What about lower budget but still works well ?

Hydrofarm is the absolute cheapest thermostat I will even mention. It's just a on/off thermostat that doesn't have the reliability track record of herpstat or helix. But it is better than nothing.
