Hi there i'm totally new to DSLR photography and since i have started a college photo course i will need to get myself a camera. I have been using a Nikon D40x on the one day i'm at college and was thinking of just getting a used one of these on the cheap so i could worry more about the lenses i'm using rather than the cam body. But since a used D40x is about £250 i noticed i can get a Nikon 3000 brand new for £299 but reveiws are not great for this camera can anyone tell me if there is that much difference with the 3000 to a D40x as you would think a 3000 would be better but not the things i have read about it. Also for a beginner is there even much between D40x to a 3000/3100 and a d5000 apart from megapixels and a live view screen? any help would be good thanks.
