There is little reason why a DSLR would be worse for battery consumption than a digital P&S, and there's no winding mechanism so there's more space in the body - I would suggest that a 4xAA system would be the best - use 2xCR-V3 for long disposable use, NiMH for everyday and if you're caught short with no power buy some duracells...
