the problem with vortex is they constantly change their models and when they do they blow out the old ones at heavy discounts. That really effects resale value. I say that and my spotting scope is a vortex viper HD. but I didn't pay retail for it and I shouldn't take too bad of a beating when I sell it, but I did know what I was getting into before I bought. ideally my strategy is to buy optics at the very best possible deal. Then I can sell and upgrade later and get nearly all or all my money back to upgrade with.
