Need a Backpack Recommendation

[Aysedasi]

I've been a traditional camera bag man ever since I owned my first SLR, but dragging the thing around Le Mans for something like 45-50 hours this year darn near tore my shoulder off. Trouble is that I use the bag for everything, camera, lenses, flash, video camera, water, batteries, raincoat, plus all those essential other bits and pieces. Having watched my colleagues with backpacks this year, a combined camera bag/backpack seems the sensible way to go.

I've been looking at Lowepro (as my last 3 bags have been Lowepro and I've always been very happy with them), I have my eye on a Fastpack 250 or 350. But I think I probably need to see one 'in the flesh' to decide if the smaller one would be big enough.

Has anyone got one of these they can comment on or recommend? Or another similar backback that's worth investigating? I don't want to pay the earth - I'm probably looking at £50-60 here.

Thanks.
