Bet you have already done that though hey...
Depends where in the country you are but Bristol Cameras have em

Have purchased there before, and have never had any issues.
Quick look on Google shows plenty of UK urls selling the item, i think it would be well worth a look, Ricoh cameras are pretty good, if the item is going to be out and about it harsher environments its perfect, gps is built in and its got a 2 year warranty.
Yet again, the Sony thing can be used with any Camera and its pretty small and the battery last half a day or so...
