I can vouch for the deep cycle battery & inverter. I have the battery for my trolling motor but I don't see why a regular car battery wouldn't work.
Auto cigarette lighter inverters are inexpensive from Radio Shack. Get yourself a cigarette lighter extension cord too while you're there. Clip...
Wish I still kept 'em. I've had all sorts at one time or another? frogs, lizards, snakes. Do go for the bearded dragon over the iguana. Iguanas have nutritional requirements that most people don't realize and they poop in their water, so probably not great for a class.
Ever hear of this guy...
