I was in your same shoes a few months back. I tried the vortex diamond back, Nikon monarch, alpen and a few others side by side at sportmans wearhouse. I ended up buying the vangaurd hd82a from Amazon (since I couldn't test it anywhere) and returning it a few days later because it lacked clarity/color and had dust stuck in the lens. So round two I bought the zen Ray ed2 20-60x82 and couldn't be happier I hate to say I like it more than any vortex spotting scope I've looked through and only paid 799 with a tripod new.
