No, purely resistive. Although it does have a "boot up" time, I think it's just
due to heating up the element. I'm not completely sure if the element will
respond better to a "dimmer" type set-up (running it at less than normal
voltage) or a "pulsed" set-up with a relay... but with the relay I'd have
all-electronic NXT-based control, which I really like.

Wow! Thank you, I didn't realize they made those (although they aren't cheap...
but it's at least viable).

Thanks for that tidbit as well... I wasn't aware of that, and was worried about
it.
