My girlfriend knows a guy selling his Nikon D60, and while I'm a Cannon fan, I'm definitely interested in checking it out to see if its a good deal. The thing is, I don't know enough not to get potentially scammed so I was hoping someone could maybe give me some pointers as to what to look for to make sure its not damaged or has something wrong with it. Also, what would be a fair price for the camera used if its been taken care of? Thank you for any help you can offer. Sorry for...
