I am just getting into photography I've shot maybe 10 rolls on my Nikon FM10 and 2-3 on my Mamiya NC1000. More to the point I love these cameras (read I like manual cameras) but film and processing costs start to add up when you're a college student. I think I can convince my Dad to get me a dSLR for Christmas but the budget would be pretty low. How poorly would my money be spent if I told him to get the D40 or the D40X? Is it worth the risk to buy a D50 or D70 used? My Dad currently uses a D70 and has a couple decent lenses for it so I would like to stick with Nikon unless there is a much cheaper option that is better.
