I had to replace the secondary in my 10" hardin dob when it loosened from the support and bounced off my primary, chipping an edge of my primary and destroying the secondary. The secondary appeared to be secured at the factory by a half of drop of elmer's glue-all or equivalent.
At any rate, I ordered a replacement from Scopetronix a couple of weeks ago, despite some reports of it's demise, and I received it today, well-packaged and ready for installation in my dob.
I also had received an automated acknowledgement of my order a few days after I place it.
I was a bit apprehensive after reading the posts in this forum but I didn't experience any particular problem with my order.
