At this point the type of photography I want to do is pretty eclectic. I like macro, graphics, flowers, landscape, and anything that says to me "shoot me". I walk around a lot.
I don't see why this would not be a good lens for a crop sensor camera. However, in my opinion you would be better off with a macro lens based on the type of photography you are interested in. Given your budget, that, plus the 50mm you currently own should cover your most of your needs.
PS: If you are offered this for $300, chances are this is an older version of this lens, not the USM version.
