I bought the CenterPoint 4-16x40AO from Wal-Mart for $69 plus tax, and it's on my Hatsan 95 vortex. .25 cal sitting on an Instapark 5-screw one-piece base from Amazon. I've put about 100 pellets through it, and it's holding up nicely. I've had good luck with the CenterPoint scopes, and they stand behind their warranty as well.
