I just got a burris c4 with 270 turrets from natchez fro 139. I think the clarity is very good for that price. I have few nikon's and vortex's and I would say it is better than my prostaffs which cost more and same or better than the diamondback. Its not a viper or monarch, but close. for the money its the beez neez

All of them do something better than the 30-06, but none of them do everything as well.
