I'm planning on starting a beginners photography course in September but don't know what kind of camera to get. I want a DSLR or SLR whichever is best? For around £350 and one that will kind of grow with me if that makes sense, so as I advance into intermediate and advanced I can begin to use new features with it such as new lenses etc. Any ideas?

There is a WHOLE WORLD of difference between SLR and DSLR so you cannot compare between the two.

They use TOTALLY different mediums for taking the pictures and as such have utterly different fearures and capabilities.

But I'm sure somebody [else] will be along with a handy link for you.
