I like my Nikon D80. It ain't the D300, but it's going for pretty cheap right now w/ basic kit lens. I do a ton of low light concert and show photography and have used the 50mm1.8 prime ($100) and the 85mm 1.8 prime (about$399). They are both excellent for low light photography and they AF on the D80. I tend to use them more often than not in Manual mode anyway, but that's just my choice.
