£100 is pushing your luck a bit, think £600-800. I have a Canon Legria which produces amazing pictures for the price and size of the camera. The current version is the HF S200.
Don’t forget that you need good sound too, and the Canon has an external mic socket. It records on SDHC cards – probably the future medium for everything below the feature film level. The format is AVCHD – a bit of a pain – but I get it in to FCP using Clipwrap.
