I've been reading a good bit on DSLRs and the latest crop of Nikon/Canon products, though I'm partial to Nikon. I'm by no means a "professional" photographer it's just one of my hobbies. I currently use a Nikon N55 with a Kodak (bleh - it's crap, I know) 80-210 zoom and a Sigma 20mm F1.8 wideangle. Cars are my thing mostly but I'm expanding my subjects . I'm caught between the D80 and the D40 simply because I don't know how important it is for me to have a focus drive motor. Am I really going to miss it? I hardly use AF now anyways...Is it worth it to drop the $1K for the D80 just in case it has some feature that the D40 doesn't, something I find out later that I really want/need? Advice, anyone?
