Blimey 2007.....so many bikes and so little time.
I've seen a lot of good condition systems for sale in Japan recently but they're just too big for regular shipping, if only they made it a two or 3 piece. I could see if I can get 4 or 5 systems slotted in a crate somehow but it's the storage thats going to be the problem.
Still got my Kerker that I bought new, sold to help pay for the Yamagamma and then bought back again! I keep my eyes open for another but that's the only one I've ever seen.
On a brighter note, I can get hold of repro CB-1 stantions now:-
