You could use a printer or copier fuser unit.
I use one with great success and we have some other positive reports too.

You need to find a old/dead printer/copier, or buy a replacement fuser 
unit.
Then you build a simple temperature control circuit (often this is found
in the printer or copier).
you also need a motor for it unless you want to hand-drive it.
i use a motor which was intended for rotating a chicken grill.
It has huge gearing ratio and a lot of torque, and it is slow.
I need only 1 pass with this motor.
