Just to follow up, I picked up a 180 Componon-s and it works like a charm. I'm now able to print on 8x10 easily.

As an aside, I bought the lens used from Robert White for an appropriately discounted price. When I got the lens I was shocked to see it was still shrinkwrapped in the original packaging. The cardboard box had been opened, but that's it. I have no doubt that any of the US dealers would have sold the lens as "new" -- which is pretty much exactly what it is. I can't recommend Robert White highly enough.
