Bruce, I just bought the Philips SPC900NC from Peter Tan in Hong Kong. Website is
www.tan14.com/gears.htm Cost me $84AUD (including postage) and that included the telescope adaptor. Was delievered in about 4 days. Great service. Thought this might help.
Of course it's still in the packaging because it never stops raining in SE QLD!!
Cheers
