My partners and I are considering this preheater:

It's advantages seem to be that, unlike Tannis and other sump
heaters, it's not permanently attached to the airplane, and
therefore doesn't require an STC or W&B recalculation (unless
you forget it and leave it attached :-).
Anyone ever use something like this?

Here's what I did:

Cheap 1500 Watt heater from Kmart fits neatly between nosewheel and
lower cowl.

Maybe I'm missing something, but the heater you point to strikes me as
another typical aviation ripoff: Take the normal price you'd expect
something to cost (in this case I'd say around $30), then multiply by
10 to get the actual price because it's for an airplane.
