Cheers for the input.
I do have a Nikon (L310), but am looking to make the jump from a compact to a DSLR.
This review compares the 3200 to the 3300. I suppose the 3300 would be the most up to date version of the entry level, while the 5300 or 7xxx models would be out-with my price or level of expertise. I don't have a hard budget, but I do want to consider an additional lens or two, and I think that £500 is a reasonable starter budget. I came across this as an example (D5200 in this case):

Now a kit like that with the 5200 might be better than a 3300 for all I know. I'm just browsing at present and happy to get 3xxx v 5xxx v 7xxx information (other than price).
The L310 is a great wee camera for the general stuff, but it is limited in several aspects (a lack of a proper manual mode being one example). Hence why I'm really looking to step up a little.
