Homebrew PCBs

That is certainly the case with modern programmable ones, but older
surplus controllers will often only work with one type of thermocouple
and some only with certain thermistors, so take care there. Old
surplus stuff can be a lot cheaper, but one needs to watch out for
that.

For fusers/laminators a thermistor control seems to be perfectly fine
anyway, and that can be done with quite a simple homebrew circuit if
one doesn't like spending the money.
