[TenTec] Need advice on purchasing used Omni VI

[BILL GREEN]

I became a Ten-Tec fan when I purchased a used Argosy II  525d 
about 5 months ago - what a great little rig! 
I am considering purchase of an Omni VI.   Reading comments on
the merits of Opt 1 vs Opt 3 (omni vi+) have left me somewhat
confused.  Some have commented that opt3 or Omni vi+ have
birdie problems.   Could someone comment concerning Opt 1  VS  
Opt 3 - specifically, which would be better for weak signal cw dx?
Secondly, what is the going price range for an Omni VI + 961 ps 
and are additional filters still available from Ten-Tec?
I would appreciate any comments and advice and you can email
me at:  htgyyw5 at hal-pc.org
