The current 30mm offerings from Kahles are much more expensive than they were just a few years ago, especially the slightly older 1" tubes that can be found in the $500-$700 range. Is the glass in the the newer models noticeably better?

I am not happy with a reticle change they just made. They put in a #4 and the resolution of the scope is not quite at good. I am a bit put off by them at the moment as no one will answer my emails...
