Hi all, I need some help, I know this is on the low ($) end for a lot of folks but not really for me. I am currently researching a Vortex Diamondback 20-60x60 spotting scope and 2 Alpens, 745 and the newer gem series all are 20-60x60. Anyone have any experience with these? I am going on a mule deer hunt soon and need/want one but can't afford over these price ranges. The vortex costs more but is it any better, the Alpens have received awards. Thank you very much.
