I’d agree with seavers. Not too familiar with Nikon, but as far as Canon go, something like 400d-550d and anything in between. Whatever suits your budget. You could go all the way back to a 350d, which you’ll pick up cheap as chips, but it will feel a bit dated compared to some of the more modern ones. I wouldn’t go further back than that,
Alternatively you could go for a xxd series, like the 30d or 40d. These were pro-sumer models in their day, came with magnesium bodies, built tougher, larger and weigh a ton in comparison to xxxd series, but in my opinion have friendlier controls to more experienced photographers (possibly not so much to a novice).
Lenses are the important bit. I like primes myself with a fixed focal length as opposed to zooms, but it’s like asking what’s better, hardtail, or full suss…or fatbike! The standard kit lenses aren’t the best though in my opinion, so it would be worth doing a bit shop around.
mpbphotographic.co.uk will give you an idea of prices, if nothing else.
