Re: Which scope
I recently bought a NXS 5.5-22x56. I did a lot of forum hunting and bought a gently used one. I ended up going ZS and am glad I did. I definitely don't need it, but it is a convenience feature that I use (and like).
In my search, it seems that the ZS holds most of its value on the used market. They generally run about $150 more than the non-ZS used (roughly). The HS turrets on newer models also command a premium over the older 10 MOA turrets.
I think you will be pleased with your new NF, ZS or not!
