I have a budget up to 1300$ at most but if i cani could get 1400$ (long story) I was looking at used Mark II's for anywhere from 800$ to 1400$ i have been watching them sell from that range. This includes some MArk II N's. Is it worth it for a MArk II or a 40D new ??? then buy a battery grip which one is better??? i already own an XT and is wayyyyy overdue for an uograde. thanks other suggestions either used gear is fine. Thanks
