Best Laptop Bag?

Hi, I haven't posted in a while and I'm sure this gets asked a lot but while searching through past posts I wasn't able to come upon anything too up to date. My home was recently robbed and of course most of what the robbers took were my apple products and accessories. I am in the process of getting new stuff, as well as a security system, but the one thing that really ****** me off was the fact that they stole my backpack for school. It was an Incase Sling bag that held my macbook pro, back up hard drives and power adapter. I really liked that bag as far as the size, but I have never been a fan of sling bags because of the uneven amount of pressure they deliver to one of your shoulders. I was at one point contemplating getting the Incase Nylon Slim Backack because it was very similar in size as far as the compartments of the bag are concerned, and it evened the pressure between both shoulders with two straps like a traditional book bag. Anyway, I went to Incase's site and apparently they stopped selling that bag, which leaves me with no idea on what bag to get next. I want something stylish but is thin and not too heavy, but will allow me to carry around my new laptop, some magazines or a small 3 ring binder, my power adapter, and maybe some compartments for a wireless mouse, pens, and a keyring holder. I'm familiar with STM and Timbuk and most of the brands offered on the apple store, but haven't found anything I like, and the Incase Nylon Bag offered on the Apple Store site is way too big for everyday use. SO my question is this, where can I find a bag that is similar to the Incase Slim Nylon Backpack, has as much simplicity and style, and won't break my wallet in this trying time?

With great appreciation,
