Since you're a college student and on a tight budget I say go for the onkyo or the yamaha mentioned above. Stay away from brands like: Sherwood, kenford, Rockwood, Kenwood, and Sony. Although Sony and kenwood make some good stuff I just don't think their receivers are up to par.
Onkyo, Dennon, and Yamaha seem to make the best Receivers IMO.
However, if you decide to save up for a good one you could get a really good receiver for around $700-$800.
