So this is my first post! Anyway, long time D80 user looking to move to a D600 (I am over the dust issues and figure the IQ is worth cleaning a sensor). So narrowed down to amazon and crutchfield (mostly because I can use my AMEX points). I've read post about people believing that amazon may sell returned items as new (amazon.com as the seller, not third party). Anyone know any info about crutchfield? Anyone buy there D600 from either one?
