No experience with the Prostaff line, but my Nikon Buckmasters have held up well. Don't know what price range you are talking about, but Natchez Shooters Supply has a closeout sale on the Prostaff 4x32 rimfire scope in realtree camo for $69.95. My luck with cheap scopes has not been good, but then, airguns tear up the best of them if they are not designed to take the double-recoil.
