Well, it depends. I don't go out and buy gallons of stuff just to try it out; I'm usually looking for particular recordings, or at least particular artists. So I tend to prefer shops that actually sort their records--and I pay for that service. Even so, I've picked up plenty of old rock for $2-4. I'll go somewhat higher for jazz, but not too high, because used CDs are less than $10, and I'm not a true vinylphile.
The exceptions are out-of-print stuff. I recently picked up "Delightfulee" by Lee Morgan for $15, and I've spent as much as $30-35 for Yardbirds rarities. (Though now I listen almost exclusively to the excellent Repertoire remasters on CD.)
