Dude you seriously need to calm down. I'm a college student too. I ride a couple miles a day for fitness, and to do errands. I bought a Critical Cycles fixie on amazon for 200, because I didn't do research first and it looked cool. Is it the bestest bike evar? Nope. But it rolls, and it gets me off my ass and outside. My suggestion would be to find the cheapest you can that has what you NEED, not necessarily what you WANT. Then get out there and ride the hell out of it.

Best of luck.
