After googling around, I discovered Vanguard Spirit XF 8 x 42 binoculars. They're pretty highly rated for beginners, which would meet my kids' needs. Does anyone have these? Like them? Dislike them?I am also considering a couple of pairs of Nikon Monarch 8 x 42s like my own -- partly because they're good and partly because of Nikon's lifetime warranty.I'd appreciate any feedback about binoculars for an elementary birding club.Thanks.Julia
