RE: Help me choose
I would opt for the 3200 elite myself. I'm not overly impressed with the VXI's, I have even heard some leupold fans say they are not that great for the money. The one thing it would have going for it is the waranty.
If you can look through each then decide. I will not buy optics whithout handling them first.
Never heard of Nitrex so I can't give an opinion on that.
I will add that I have a Mueller and am quite happy with it for the money. The Cabela's Alaskan Guide scopes are pretty nice as well.
