Hi IanW,
Thanks for the information i will check out scopehead. I have looked at the telscope warehous website and noticed only DS motors. But as you say i may not be able to get LXD ones. So may have to make do with DS motors. For a worm i found a new cheap source with some credibility. Gototelscopes in America is now doing cheaper HDPE gears. But i am not sure what it would cost for the worm and the gear.

PS: i think there was some here advertising DS motors also. I will do a search and see if still available.
