I recently picked up a Nikon S3000 (around £100) which seems decent enough so far. The only down side for me is that it has a rechargable battery, so you need a power socket if it runs out.

My previous 'pocket' camera was a Canon A95. Slightly heavier and bulkier as it uses 4xAA batteries, but the screen folded out which was nice for composing 'awkward' shots at an angle, high/low views etc.
