[Ruption]

Hi my name is Scott

New to this forum, join because im looking into getting back into photography after many years away from it.

basically Im looking for a good around camera for around £350 to £400 if possible, and where to shop from? as my current camera is on it way out as the flash is very temperamental about when its going to work and when it isn't. i currently have a DSC-F828, so just looking for something close to or more up market from it

here is an image taken with current camera
