What is the best stick vacuum for carpet and hardwood floors?

I'm a college student and my dorm next fall semester is going to be pretty small. I would love to have a vacuum and thought of a stick vac. I'm not too familiar though with the stick vacuum products. My dorm room is carpet but I want to get one that will also be good with hardwood floors. Lastly like I said I am a college student so I need to get the best bang for my buck. Feel free to leave reviews of the product.
