New compact digital camera?

[puggit]

Looks like we've fallen foul of the Pentax curse of the 'depleted battery' (do a Google, I'd avoid Pentax digital cameras if I were you...) on our Optio S40. Bought in Dubai 2 years ago, so little recourse for action.

So we're looking for a new compact digital camera, preferably one that takes SD cards. Any recommendations?
Budget around £150 I think is fair...
