Brent,
  I certainly agree that Kirk Hammersmith is the go to guy for the Sierra
2000 System.  We have an early production version and it is just great.  I
think it is one of the first twenty production units.
  Kirk has bent over backwards for us.  He is backing his panel and your
system fully.  He flew in here to Tehachapi, CA last Tuesday to give me
support on the system programming.  My owner and I (as the builder) are very
impressed both with the CFS Synthetic Vision Flight System and Kirk's work.
  We first saw the system at Kirk's insistence almost two years ago when we
flew with Nate in the Cessna 210 demonstrator.  That one flight was all it
took for us to see the value of your system.  It is beyond words from one
who learned to fly with a mic in hand and an overhead speaker in a Cherokee
140 which was new at the time.  Things have come a long way...
Sincerely,
Walter Dodson   IV-P N990Y in flight test
