They are still sold new, yeah, as far as I know. Check camera shops around your area for 'em too. There was one at camera solutions inc here in portland for a long time but it seems to be gone now. I don't think the AIS contrast compares well to the contrast on the 1.8g, but it does have a diff dreamier look. At f/8 though I bet no one could tell the diff.
I don't even bother with the one shop here that sells used gear, their pricing is ridiculous.
The 50/1.2 I had did very well on the D700 and the contrast was very good, if I have the time to set up a shot I would take it over the 1.8G. I have the 1.8G and will pick up the 1.2 when I see one for a good price.
