I own a couple Weaver scopes now, all of the newer variety. I don't own any with as high a magnification as you've mentioned however. I have two 3-9x38s (V9), a 2-7x32(V7), 1-3x20(V3) and a 4x38(K4). I cannot say that I've had a problem with any of them and actually have one of the V9s atop a very nice custom rifle. I think the new Weaver scopes are a very good value/$$ actually.
Good luck with whatever you choose.
