Picked one up last year in a go outdoors sale for £45... It's a good bag. The lid is however really annoying.... You can fix it easily though by clipping the daisy chain on the lid to the daisy chain on the main bag with a carabiner.
Downsides? The slits in the belt loop don't allow your harness loops to go through if they are slanted... I would have preferred they just stitched on new loops! It goes rather narrow to the bottom, maybe too narrow? personal preference and being picky there really. Also I'm not sure why the waist strap has so many buckles? gets a bit fiddly... once again I'm being picky!
It's a really light bag, cant really go wrong with it
