Think I just answered this one at OT too. Those Steiner Peregrines are not "almost alpha". They are alpha class. I would take one of those as my first choice in an alpha class glass. In my case it is mostly ergonomics. Nothing feels as good in hand as those do. Optically the differences are mostly differences in color bias, that and you never know how any given set of eyeballs will react to any given binocular. I Think a Swarovski SLC-HD is the best image in the alphas today (but not enough better than the Peregrine XP or the Swaro EL or SLC to be worth $2k...and I have yet to see the new Zeiss). The rolling ball effect in the new Swarovision EL's gets the best of me and I would not keep one of those any longer than it took to sell it. If you can get a new condition show demo sample Peregrine for $700, that is half price and qualifies as a deal in my book. Those things define "alpha class durability".
