I’m looking for a warming pot than can be used to keep chocolate in temper that I can get in the US
All of these small melters do have thermostats. There are two sizes in the Waring Pro line – 3kg and 6kg. Here is a link to see the specs for the 6kg machine and purchase online:
There are also replacement temperature probes. Temperature range for this machine is 68F (20C) to 140F (60C).
