12V battery voltage datalogging device recommendation?

Can I get a few recommendations for cheap devices I can use for voltage data logging over a period of days. I don't have a dedicated instrument or tool, and am quite handy with electronics, etc.. so I could make one, but any leads on a cheap useful ready made logger? Maybe built as a USB stick or something to make downloads dead simple... if it had ambient temp logging builtin, or an aux analog input that I could hookup a temp gauge, that would be swell.

So ya, logging voltage, maybe temp, over time is what I'm after. Sampling period of maybe 10s or 30s would be more than enough. Storage space for 3 days sampling.
