I wouldn’t really consider sharing a plane for couple reasons: I don’t really know so much anybody who flies here. A plane is a robust but sensitive machine that needs more than love and care, I couldn’t be bothered liaising with anyone to see who did what on it.
I'm exactly the same which is why I owned my aircraft (3 overall) myself.
My last aircraft change I had a choice between a 3 year old permit all glass construction with a glass instrument panel - total glamour aircraft, and a PA28 a lot older. I chose the all glass model but wish I had gone for a regular PA28. Reasons for this are simply that everyone knows about a PA28, how they fly, how they engineer etc and they have a fairly fixed resale value. With a 'special' aircraft you just don't have this wealth of experience.
Good luck with your choice. I have to admit that the most FUN I had out of flying was my first three-axis microlight !
