This is a high temperature (up to 105'C) Food grade mini water pumpThe shaft is coated with a layer of ZrO2 (zirconium oxide ) for higher temperature handling and better tolerance for acid and alkalineMade in China
Since you seem to know what you're doing why not get a non pc specific pump? I know they make small submersible pumps for fish tanks that are very low volume/min and take up nearly no room.
here's a tiny one

Good call. This one's a bit cheaper, if you wire it yourself. Then OP could afford a roaster oven to and a circulator pump to use it with.
Heres a good pump http://www.amazon.com/temperature-15GPH-Water-Pump-grade/dp/B004HHW0FU/ref=sr_1_1?ie=UTF8&qid=1341652283&sr=8-1&keywords=hot+pump
Dammit, I closed the wrong window and have to retype this.
I wouldn't use a float since mechanical stuff like that has trouble, especially if your water is hard. I'd use a resistance sensor, and if it's over a megaohm or so, shut down. As long as you don't use distilled and deionized water, it should work fine.
High temp pumps are expensive (although low temp pumps are cheap, they won't handle 80C). It'd be much cheaper to mount a small motor to spin a paddle in a housing. I do have a bookmark of this guy, which might work though.
I was looking at this site to get an electronic thermometer. I think they have I^(2)C sensors, but haven't looked lately. Sparkfun has a cheap one but that loses accuracy higher than 85C, which might be fine. Generally, within 1F is good enough. I'm just pulling some bookmarks and going off memory....
