looking for a full de-iced late P model

[Brent]

Does anyone have any leads on a P model with full deice? I've been flying a P210 for the last 20 years but feel it's time for two fans, and the P337 seems the only practical solution. I need the pressurization as the 'minimum sector altitude' about 1 mile from my home airport is 16,000msl, and I run into enough ice that the boots are a must. A good solid maintenance history is also important to me, and good radios would be nice, but run-out engines are ok.

Is there any truth to the rumor that 'plumbed' for boots means nothing since the parts are no longer available to make a new deicing boot installation? That you can replace parts on existing systems only?
