i just upgraded from nikon monarchs to vortex razor 10x42. phenominal glass. also i think that you can still get a$100 rebate if you buy soon putting the price tag at $660.
Look them up on the birding websites, they get great reviews and ar oftencompared to the alpha glass with half the pricetag.
Also, after looking through the razors i cant imagine how much better zeiss, swaros or leicas could be.
good luck
