I will second High Country's viewpoint on the 4200. Phenomenal value!!!
I just checked pricing and it looks like scopes took a jump up in recent months. Both the Z. Conquest and the 4200s are up from what they were last year.
Did you get a chance to look through any of the Burris Signature stuff? Just interested to see what you think compared to the other stuff. I like it, for optical quality, right there w/ Leupold. I like it quite a bit more than the Nikon stuff. Have heard other say just the opposite.
