I know this can become a very heated debate (at least, it can on photography forms), but I am in no ways looking to start an argument. I'm only wanting to hear your preference and your reasons behind it. Long story short, my beloved Nikon D3100 is on it's last leg. The lens (18-55mm Nikkor) is going as well. This is pretty frustrating for me, since I've only had it a bit over two years and I take immaculate care of it. It's used daily, but is never dirty/wet/dropped/ect. I loved it hugely before it started to go, and I love the feel of it in my hands. But if this is how Nikon's products are, I'm not comfortable dropping that much money every two years or so. Is this a common issue (it'd cost more to fix the camera than to buy a new one, FWIW) with Nikon, or did I just get a dud? For those of you who use Canon, why do you prefer it? For those that use Nikon, how has yours held up? For those who've used both, what are the major differences you've noticed?
