So with some extra Christmas cash I'm looking at purchasing a used DSLR. I'm not asking for recommendations as to brand or model, I have some clear ideas I what I'd like and what's available. The camera is likely to be used as the family camera as well as some outdoor photos. I also write part time for a bicycle magazine, so shooting some races is very likely as well. The question is is there a huge difference between say a 6MP camera and an 8 MP camera? Is that extra money better spent on the better body or saved for extra glass, flash, case, etc.
