The Diplomat from Red Rock is pretty good good. I bought one a few days ago in anticipation of an upcoming trip. It's got loads of storage space and it's pretty comfortable. Tons of MOLLE space for expansion too, if you're into that. It's the kind of pack you could take on a multiple day trip. I got mine for $60
I'm not sure how it'll hold up to abuse since I haven't used it yet, but I've had similar packs that I've used for years before they started to fall apart.
