Re: [APML] G11 Tracking problem (double star)



Hi Jon:
Very well said. When you have time (and if you want to wade through the
thread) you'll see that quite a large number of us strongly supported the
G-11---some with no modifications, some with a few, but Greg ignored these
or refused to believe them. Apparently he had some very traumatic experience
with Losmandy, but he never said what. The one time I needed a replacement
(due entirely to my own stupidity resulting in a smashed motor connector),
Scott over-night shipped a replacement. So, not only has  the mount been a
good product for me, my experience with the service from Losmandy was also
excellent.
