Thanks for your quick reply!
I am pretty sure the 200b is same as the 200 model.
Your advise very much appreciated, I now will go ahead buying this mount and fingers crossed the AN will be OK for this mount.
A conversion to a real Goto mount would set me back approx. $2500 including transport to/from Japan.
I will be in contact again early next year (2010)
meanwhile have a very happy new year
cheers
