Cody stay away from that Redfield, my son has one, and it's not half the scope that the Vortex Diamondback is, I think you can get one delivered for 200.00.
+1 for the Diamondback.
In 3x9, I have a Diamondback, a Vortex Viper and a Zeiss Conquest w/RapidZ reticle. The Diamondback has the widest field of view, which is a very good thing. The Zeiss is a better better scope but not strikingly so. The Diamondback will keep you going for several years before you outgrow it, if ever.
