I've been doing Photography for about 2 years now and am one of my school's yearbook photographers. The model they use is I think a Nikon D300, however it's the school's so I can only really use it on yearbook assignments. I am currently looking into buying a good Digital SLR myself to continue photography after I graduate, but I'm kinda broke. I'm trying to invest in one but I'm not sure what to get. The highest I'm willing to buy one for is probably around $500. What brands/models do you recommend and why? Also, what specs should I look for and what are good amounts of said specs?
