I just bought the last one from Bintel in Melbourne, $119 !
Steve is right about the action not being as refined as the older one which I already have. It seems a little rougher in the action and without tension cannot hold any weight. I think the fix will be smoothing down the roughly machined flat on the focuser barrel ala the ed80 crayford fix.
I may or may not bother with this as the fine focus adjust will more than compensate for the roughness in getting the focus spot on
