Hello John:

Thank you for your expedient reply. As a fellow business owner, that is much appreciated.

I purchased my first publication from you at the 2005 AOPA Expo in Tampa Bay. It was a Garmin GPS 296. Next was a Garmin GNS 530 at the latest Expo in Palm Springs. I just purchased another aircraft with a KLN 89B. I just wanted to let you know that your publications are excellent and I recommend them to anyone that asks.

Thank you.

Thanks, John - great service.  Your web site makes mention that Garmin's  manual isn't exactly written for we pilots and that's right - I deal with insurance contracts every day so I'm used to reading technical stuff.  I still have problems with Garmin's descriptions - they bounce all over the place and some paragraphs are none too clear.   They're not as helpful to the nuts-and-bolts pilots as I think your pub is going to be.    I'm looking forward to receiving it...  Al

then, after receiving it - 

 Hi, John - I've had a chance to review the pub that I purchased from you and wish that I had gotten it when I got the Garmin 430 in the first place.  It's written for us pilots in everyday language and contains info that is immediately useful.  Great job....and a buck well-spent.....

 These are the manuals I always wanted to write but I never had the time. They are the best help available.

 John,
I was flying home from CO on Easter. I was given an airway to fly. Used your manual in the air to load it. Not sure I would have been able to do it without your manual. Thank you,
