Fish finger sandwich but it must be the cheapest white sliced bread, loads of butter and ketchup.

I bought a Toshiba Camileo Pro HD a few months back and I'm really happy with it. It's small enough to fit in your pocket. Battery lasts 2 hours and can charge from USB. A 4GB SD card holds 4 hours of MP4 HD video. It's a bit grainy indoors at night but outdoors the image is bright and crisp. My only gripe would be that it could do with a slightly wider angle lens. But for £100 you can afford to take it anywhere so it actually gets used rather than sitting at home.
