Hey guys, I am looking for a bag (preferably backpack) for my MacBook Pro 15". I am on a tight student budget (<RM250). I will be going to a university in San Francisco, so I prefer to have a backpack as it is much more comfortable for me while commuting using public transport. Messenger bags are also considered, but backpack is my main priority.

I love Crumpler's bags but their backpacks are a little too expensive. King Single is way out of my price range, but I can't find Private Zoo in Garage Sales.

I might be considering Alienware's Orion backpack too.

I will definitely consider Targus if there are any simple, cheap backpacks.

Any recommendations?

@BRY and @dlaz:
BRY: i have the trackguard come with palmguard. imho, i like the original , better surface for touchpad.
dlaz: im just using the silicon keyboard protector, palmguard and sleeve bag with backpack. just nice to me. but if you want extra, there a see thru hard case for notebook found on garagesale. just i like it naked, but it kinda risk of getting bump.. just buy that suit to your need

I've a 5 years old MBP that is 'naked' .. only thing that look bad is the keyboard, some of the keys coating got scrapped off. I don't think you need any protector for your MBP. I've tried using that silicon protector on my keyboard and I hated it, used it for few weeks and I throw it away. And I bought the hardcase for the body but left some scratches and it looks ugly.. so, my advice is .. just let it naked..
