I have one of the 10x42m models with the side focus. I also have an older Leupold Ultra mark 4. The tasco compares relativly well with the leupold as far as durability, and precise repeatable adjustments. As far as optics, The Super Sniper is not quite on par with the Leupold, However the Leupold is three times more money. Do not take this wrong, the Super Sniper has good optics. For the price I dont believe you could find a better scope. Also I read on SWFA website there is a new scope on the way from a new manufacturer, its called X.O.T.I.C. USS, it sounds to be really good. The SWFA rep says it should be comparable to the Night Force scopes. It lists for $799.00 and will be out in the fall of 2004.
