Hi Morton,
I ordered my AOK mounts directly from AOK, Beat Kohler. He responds to mails in English and is a very nice guy.
Prices on the website include VAT which will be deducted for export orders.
When I purchased my AYO II I tossed up between the Discmount DM-4 and the AYO II. The AYO makes tripod extensions for my scope un-necessary due to its shape and was a tad cheaper landed.
As I am very happy with my AYO II for my FC-100 and Sky90, single or in parallel I purchased the AYO Traveler as a light weight air travel mount.
I am now also very happy with the Traveler and when I go to Europe in summer I will get the encoder kit for the Traveler and with my NEXUS and iPod touch I will have DSC the same way I use it with my AYO II and the integrated encoders.
Cheers.
