Thanks, Sal. It sounds like some folks on this thread feel the Apo Rodagon N 150 is the tops of the lot (contrast, fall-off, distortion, speed?) save for the mystical and reassuringly expensive Apo El Nikkor. And I was quite happy with my plain, new-style El Nikkor 150...

PKM-25, I saw that one, too. Bit pricey, I'd think, more than the going rate so far, but I guess they are rareish. Thanks for pointing out.
