All i've seen use direct mains AC.
The SSR are probably ideal.

No, not noisy. they are NTC thermistors usually. Of course you might have
small switching noise from the heater.
I do not like the idea of using a micro for a one-transistor problem, but
hey, i'm not your mother.

I cranked for a couple of boards with no trouble. But then i mounted a
"chicken grill" motor (small AC motor with heavy gearing in smal case -
cheap).
the motor is ideal as i now need only one pass.

dump the microcontroller, the rest is just perfect.
