I have emailed swfa and cameralandny for suggestions. They have recommended the Nikon Prostaff 550, and CLNY suggested the Nikon LR 1200 demos they have. There is not much of a price difference, and quite a bit of distance difference. the 50 is 6x and the lr 1200 is at 7x. Has anyone used either of these? Doug asked if I wanted 500 on steel or on game, and I don't know if I will ever get animals at 500 yards here in North/Central Texas hill country.
