Domestic toaster oven that comes with a digital control. Not as good
as a $10,000+ conveyorized oven, but probably good enough for a
prototypes. Around $90 US, I think. Personally, I'd stick an
autotuning PID thermocouple temperature controller on there, as that's
something we make, but the stock controller is probably good enough.
