There are a lot of threads on this subject already, and the search feature will be very helpful for you. However, with your budget, I'd be looking hard at the Rigol 1000Z series. Compared to the 1052E, it has 4 channels instead of 2, a larger screen, better UI, better features, and is just generally a newer design. It starts around $600US, which should be pretty close to your 300 GBP mark.
