I'm looking into getting a new camera bag to fit more of my filters and a laptop for portable uploads/editing. I found a bag at walmart.com that looks sturdy but don't know about the company. Does anyone know if Ape is a good camera bad comany? Or if they make a good product. I'll post the link if you want to see it.

I'm a big fan of my Tenba bag. It holds a 15" MacBook Pro, a 7D, three lenses and a flash unit. My favorite thing about it is that it doesn't look like a camera bag. Tenba | Laptop Messenger Bag, Large (Burnt Orange) | 638-234
A backpack bag is not something that I would buy on line. If you plan on carrying it a while you want to make sure that it fits you properly and can be adjusted to fit you the way you want for comfort. While not a big fan of backpack bags personally I do own one. It is a Lowpro. It is the only one that I found that fits my long frame comfortably. If you have a good photography shop near your location you might want to start there to find one that you like.
