I have a J107 Dragonfly
(eberlestock). I wont get any other brand of pack again, except one. Badlands superday. My brother-in-law has one and I have never seen such a little pack do so much. We went on a high country mule deer hunt at 9,000 ft for three days; 8miles from the nearest goat trail of a road in the nastiest country you can find (and steepest). His pack held almost as much as my J107, mind you I did take a few of his items, but nontheless I was really impressed. I think that its within your budget.
My other pack Ill recommend is the Eberlestock gunsliger II. great, well thought out packs.
