I bought a used Super Slam about a month ago for a rifle that I will give to my grandson (a Winchester 100 in 308 Win.). I was not ready to drop high coins on a teenager's rifle, not knowing how he will like hunting. I was impressed by the clarity. Not a top end by any means, but plenty good. As far as a Nikon "Prostaff" .... I don't think that this product is a "value". The Prostaff is not a bad scope .... but in my opinion, not worth the MSRP.
