You might be able to get your hands on a C-5060 at John Lewis, the Aberdeen store had stock of them.
Also can you not get Jessops to bring one in for you to try, thats what I did.
Also with regards the screen, yes it is a little small. BUT the fact that it folds in ever direction makes up for its size.
On the C-7070 Ace Cameras in Bristol think they may have stock in 2 weeks.
