Congrats! KEH EX rating is superb. Eventually you will find brassing, rubs and wear as you handle the camera, but it's cosmetic. BGN rating is where things look really beat to heck, but I've bought items in that category and they work like a champ. No complaints, KEH is the only place to go if you want reliable 2nd hand equipment, period.
Nikon D1 - everyone snickers when they think about a DSLR that size and weight and only shoots 2.7MP, but then I show them this photo, and no one believes me until I show them the EXIF.
