Although i havent personaly used a D70 a friend of mine has one and also a D40 and gets pretty decent images from both i liked my D80 before it was stolen along with my entire bag contents at a charity shoot a few years back . there are loads of great bargains about just now if you shop around and batteries can be purchased from premier ink or 7 day shop for peanuts just make sure you get some kind of second hand warranty and even better a recent service record and you should be ok then in future you can always upgrade . good luck
