For another consideration, if you want a mildot with MOA adjustments, I'd look at the Burris XTR 4x16 or 6x24. It's another optic with a 30mm tube and side focus adjustment, and I've been really impressed with the 4x16 we mounted on a friend's rifle. Not sure I like it more than the Vortex necessarily, but it's another worth considering. Be sure to leave room in your budget for a decent set of rings and bases as well, you don't want to spend good money on a scope and skimp out there.
