Meru, I may be interested on how you put this together for "next to nothing".

I'm using one wrapped around the 102mm Lunt but those things are 240 VAC, not 12 volt. I'm in an Ob close to the house so not a problem but obviously no good in the field. Inverters and the like are notoriously inefficient. If I was going to use mine I'd nick one of the wifes UPS's from work, charge it up and chuck in the back of the car. At 6 watts it would give about 20 hours runtime at least.
I've wrapped an old bath towel around the heater on the Lunt to reduce losses, bulldog clip secures it on. I've also thought about getting a couple more for an EP box and and also the SW 80 f11.
