I was wondering what is a good camera to get for around $500 to $600? I am mostly looking for a Nikon or Canon. I sold my D70 awhile ago to help pay for school and now I am wanting to get back into photography. I like taking a varity of pictures from sports to macro pictures. Would it be worth getting a D70 again because I liked that camera or is there new DSLRs now that would be a better investment? Thanks for the help.
