i read an article from circus magazine that said it was "closer to their old style metal" so it must be awsome!!! oh yea my dad wont be back tel saturday (hes in holland at their sarah lee plant) and ill ask him the question then. i was thinking about it and im pretty sure you can use a thermal sensor like people use for computers.. theyre digital, and so small as to not interfere with the intake movment (the probe is about the size of a hair) i dont see how you couldnt just rig that up to a switch.. the parts for that would only be like 20-30 bucks from an online pc store.. ill do some hunting tonight when i have more time.
