"NEW YORK CITY?!? Get a rope" What the heck are you doing way up there,lol?Welcome to the forum NYCTexan :^)
I'd go for the new one if it's "only" $600 dollars difference between a used and new.
Don't forget shutter counts can be reset! Is this a reputable place or person your thinking of buying from?
Hahaha. I love Texas, but NYC is the greatest. I am thinking of buying the camera off Craigslist, so no, I don't know this guy. I did google him and found his Flickr and similar info, so I don't think he's trying to pull a fast one. And of course it would depend on seeing the camera in person, with my 24-70 on it, giving it a good inspection.
I didn't know shutter counts could be reset. That's mildly terrifying.
Oh and GO HORNS!!
