Not even sure is there is one of these in the country
Even a search of astromart auctions shows only 4 listed over the last 7 years and they were all by the manufacturer Markus Ludes.
Have you tried talking to Markus Ludes at APM telescopes? Another person who may be able to help you track down something quite rare is Herb York from astromart. With the aussie dollar strong and the US/euro weak it may be an opportune time to find an overseas seller.
Best of luck in your search
