I also go to college and am a DJ. It all depends on your style and how much you can spend. It's not a cheap thing to start. I agree with the B-52 Matrix 1000 system. I picked that up when I began. It is expensive though. But what you need to sit down and think about is what kind of equipment you want to use. CDJ's are good way to go because every club across the world has them. Digital DJ-ing is beginning to become more and more popular, but you need more equipment than you think. At least a laptop, a program (virtual Dj, ableton, serato, etc.) Vinyl is cool, but only if you have the money and ability to hawl all the records around…. plus, it's a pain to find those good songs on vinyl.
I will suggest this, think about how pro-active you want to be as a dj, are you looking to perform and interact with your equipment. i.e. show some skills. Or are you just looking to mix on a screen, that usually beatmatches for you. Either way you are going to have to get a mixer.
Look at Pioneer CDJ-200 or CDJ-800. Thats the industry standard. (1000 are too expensive) And then go out and find a good mixer with lot's of capabilities. (digital in-outs, plenty of masters, and booth.
Also Try going to a your local shop to feel around with what you like.

Nice used equipment for cheap. You don't need to be dropping $$$$$$$ just starting out.
