Reply to Backpack/Bag for carrying around a MBP and an iPad

I'm looking for a good backpack to carry around my MBP and iPad plus other gear/items. I don't mind paying unto 100$ maybe a little more. I looked at some they had in the Apple Store and I refuse to pay 150$ for an overpriced bag that wouldn't hold much more than those two things and a single book.

Anyone found a good quality bag that has space for both items to sit securely and safely? It doesn't necessarily have to be a backpack but it would be preferred.
