What I would NOT recommend for sure, is this SR5xx clone, which has significant flaws:

As it came, the heat can't be controlled at all, there is no SSR inside, the lo-mid-hi heater knob is there only for display, power is full always, turning into charcoal the beans in two minutes.
Even worse, the heat is so big, about 400 C, that the chaff collector, made from bakelite, cracked at second attempt.

I have one atm on the workbench, to replace the whole electronics with a custom version of TC4ESP.
