Third question: How do I do the temp control cheaply?


A salvaged electric cooktop controller works pretty well. It's a
proportional controller, i.e., the higher you set it, the more the
current is "on" in comparison to the total on-off cycle. You have to
experiment a bit to achieve a certain temperature, as they are not
thermostats. These are 240v units. Old cooktops are easy to find, and
when you snag one, you get a controller and 3 spares.
