Beghaus C7
My new favourite bag. This one is retailing at about £80, and comes in blue as well as grey. Its got a wicked frame, and is quite big and skinny, but unfortunately it has side pockets which spill out, making it really wide and a bit clumsy (if they are full). If I went with this one, I'd need to keep a check on how much stuff I carry around with me, but its definitely one of the better ones I've seen so far...
