That is my favourite scope, use it on my .22-250. Have only used it for one season, but have nailed more Jack rabbits this season than ever before.
Solid construction, dependable turrets, good glass, rain coat and a nice bright mildot reticle.
I got mine for $350. $450 would be slightly overpriced, shop around and try to find one for under $380 if possible.
One thing to look at is the weight of the scope, it isn't going to be an extremely light scope.
Love mine
