Camera Backpack Suggestions

[Rockape]

I'm looking for a backpack to take my dslr. I've got a Lowepro shoulder bag which is fine, but am looking at something for day trips and a week away. I would like it to duoble up and be able to carry other bits and bobs, like a bottle of water, book, phone, the usual bits you take away for a week.

Ideas, I looked at the Lowepro Orion, which I though would be fine.

Just looking for suggestions from those who already have.

£50-60 to spend.

I have the Lowepro Fastpack 350 when I need to carry loads of stuff. It takes all my camera gear in the bottom section, and loads of extras in the top section. Its comfy enough too.
