I would think that a good motor speed controller or variable lamp brightness
control would work great.  It would not have any temperature feedback, but
would certainly have some control of the temperature of the tip.  Another
way of doing it would be to use a ac-dc converter circuit and then use
a variable current source circuit with thermocouple feedback from the tip
to get very good control.
