A few comments on the above
T tail Pipers
Moving the tail upwards was a cosmetic change, Piper said it was to move the tail out of the propeller slipstream for a smoother ride. The usual comments about the way the thing flys or rather lands are down to the fact that it is easy to fly the aircraft with the C of G forward of the Forward limit if lightly loaded (very easy to do on the PA32 & PA34). If you load the aircraft near to the centre or towards aft of the limits the aircraft fly & land well.
Piper parts
No problems with the PA28 & 32 but the PA38 is a problem, as for the Comanchie I cant comment but the very active owners club in the USA seems to indicate that Piper no longer have a good stock of parts.
Cessna 210
"it sucks" is a hard to quantify! Having flown the Cessna I could not think it is anything other than a workmanlike traveling machine, it flys safely without vices. I cant get excited about is but it will do what is says on the tin!
