I have a D90 Body and im selling it to upgrade to a better body. Ive used it only a few times and can prove the low shutter actuations. The camera is in PERFECT shape. i have all th instructions and warrenty cards but i have no box. It does come with a case and 4 gb sd card. Im asking 800. fell free it email with questions or if you want photos.


Is the D90 worth the extra money or should i go for the D80 because money is a issue?
Thanks NS
