I have the 56mm. It's a very impressive scope. Very good glass. But I like to keep one thing in mind. While it's great and has a lot of "wow" factor...would that be the case if the regular $460ish price was paid? I doubt it. Still, in the $460-$550 range it's competitive probably better than most in that range, but not something to get excited about. Which is why they're being blown out probably at 1/2 the price. Around $500, I can compare it to a Conquest 3-9, and the Conquest is optically superior. Although, the Weaver has some features such as illumination and the turrets, oh yeah and a side focus. But I don't really value the side focus that much on a 2.5-10x.
Under $300, there's simply nothing out there that can touch it. But that's true of anything if the seller were going at wholesale or less than wholesale. The web would be raving over the Nikon Prostaff too if someone were selling them for $45.
