Looking for some info about the Zen Ray line of optics. I am in the market for some new binoculars and am on a limited budget of around $200. I am looking into getting the Zen Ray ZRS (Summit) in 10x42. I have a buddy who is really happy with a set of Vortex Diamondback's and they have a warranty that is really tough to beat. However, I have heard a lot of good stuff about these Zen Ray ZRS binoculars. I have heard they far out perform what you would expect from them considering their price tag. Unfortunately for me, there are no dealers in the Missoula area so I can't check them out myself. Any input is appreciated. Thanks
