Scott,
I have one I've had for awhile (almost 10 yrs) and have never had any problems out of it. It tracks well and keeps it zero. I have had it on a .22-250, .223 and now a .270WSM.
Not sure how much come-up or MOA it has built in but then I haven't used it to shoot over 500yds.
Is the scope you're looking at used or new? Does it come with two different windage/elevation turrents? One set looks like it is made for target shooting, the turrent is V shaped and doesn't use screw-on caps. The other set has screw-on caps.
It is definately a good scope. Not sure it's worth that much money now. I say that because I'm not sure they make this scope model anymore. Does it come with a factory warranty? JohnnyK.
