After the battries ran out on my suitcase-cam on our Mournes walk I decided to think about another camera. Recommendations seem to be in the shape of Minolta Dimage G400 Digital Camera
Looks like it's available quite cheaply too (thats good for me) Pricerunner tells me it starts from about £158, which is more than I hoped to spend, but if it would be a great camera it may be worth it.
I like the idea of a compact camera, carry everywhere, and snap away at my convenience. Lets get that gallery filled up!
