17 inch laptop bag for college with large capacity

I am getting frustrated with my laptop searches and am out seeking help from other wiser backpack connoisseurs. I'm looking for a backpack that will fit my 17.3" laptop as well as other school supplies for college. I would prefer a more "polished???" look I guess -- I don't want something too bulky and would prefer to it to not be made of athletic bag material or have any strings/extra buttons attatched to it. I am looking for something that will be no more than $100 if possible.

I know that my specs are a little picky but I have issues with the way bags feel while I'm wearing them, any suggestions would be greatly appreciated!
