Always good to review this subject - especially at this time of the year.
As always, what do you want to do with it? These two posts give the message. Your price range is too low for serious photography. Even a "toy" costs £40-£50.
Which? in September reviewed Digicams. You may be able to read it in a library or borrow.
Best buys, both £280, closest to your price range were:
Nikon Coolpix 3100
Sony Cybershot DSC-P72
But don't be put off if all you want is a point and shoot device to supplement the "real" photography. There are decent models about. Jessops will advise.
At this time of the year there are about two new cameras a week so its very difficult to keep up to date. A proper shop is the best place to find out the latest.
