Cdminter59, you are absolutely correct
and, at this point, I am seriously considering getting the big boy. Although I am looking at the 8365.
However, having said that, I am a dog with a bone now and I am really interesting in figuring out why my mechanical stop is not working
so I'm going to play with it a while more before going ahead. if it works for everyone else then I should be able to get it working !
Thanks for info folks; I'll adjust the secondaries.
