Not sure what he's going to be able to get in that price range, but he might want to start by looking at Campmor and REI house brands, then move to the sales at Campmor and REI Outlet. Kelty might also have a bag around that price. He's probably not going to get down for what he's willing to spend, and I haven't priced synthetics in a while, so I don't really know what's out there.
