BTW, my sale of a clean Summicron DR for $125 on PNET was probably one of the faster sales last year. I've got the 50mm M-Hex and its outsatnding - both in image results/bokeh and in the incredibly tight tolerances, which make many Leica 50mm lens appear sloppy (I've owned 3 Leica Crons). Granted, while some Leica lens tolerances may be sloppy, the glass is top of the line. I'm sold.
