A number of years ago I decided to upgrade to a smarter aircraft.
In my mind I had a choice of a Piper quite a few years old and a virtually new 'home made' all glass smart looking aircraft.
I chose the new smart one and regretted it from day 1.
A nice PA even if a few years old, would have been a doddle to fly, would have had any engineer capable of repairing it and spares all over the place. And I knew the PA's inside out (well almost)
Because I wanted something a bit 'Modern' I ended up with an aircraft that was as slippery as hell and difficult to land. I was never happy flying it and found myself making excuses not to go flying.
I have always loved PA's should have gone with that.
Anyway, one piece of advice I will give you is not to buy it on your own,. Yes, it's nice to have it all to yourself, to have it always set up as you like it but I found that sole ownership was a lonely business. No one to discuss things with you and no one to talk about the little buzzing noise you hear.
Good luck.
