There's an APO Rodenstock N 150mm on ebay now. $600 start bid//$800 buy now. (http://cgi.ebay.com/ws/eBayISAPI.dll...tem=2928720821)

Is this worth the signif. cost over say a Componon S or regular Rodenstock? These go for $150/$120 respectfully. I'm leaning towards holding off, but it looks extremely sharp.

Thanks for any opinions,

Chris
