Hi Hannah, you know the EOS 1Ds MkIII is on that list, wish I could have one for £300 lol.
Seriously, Else is right, it's good to hold the camera first and make sure it's comfy, I was lucky as I got to have a go with my Grandad's D80 before I got mine. If you're worried about the hard sell, just don't take your money with you to begin with
Do you need a compact camera? The reason I ask is that any DSLR performs well, even the cheapest ones, there are loads of great photo's on here taken with Nikon D40's and Canon Rebel's and they have auto modes to use until you get more confident.
