It's been a few years since we flew the Cheyenne II, but Piper did not support it well back then. We bought most of our parts from Columbia Air in Connecticut.
Our SAS was worked on a couple of times and had to be replaced because it stopped heating. We replaced the brushes every 50 hours on the re-circulation fan motor (one time it went out and filled the cabin with smoke). We adjusted the fuel pressure (90 to 115psi) on the heater monthly to be sure it would light off.The heater was designed to work on avgas and with kerosene everything must be perfect or it will not light off at altitude.
The II has -28 engines same as the King Air E-90 & A-100 and moves the little Cheyenne very well, but run out of steam in the 20,s. The IIXL has -135 engines same as the King Air F-90. The IIXL offers more room, better performance at altitude, no SAS, no kerosene heater, a quieter ride for passengers, at an extra cost. If you can afford a IIXL you will like it much more.
The II is about half price of a Conquest II and much less than an E-90. I think of the II as the next step up if your flight department moves up every two or three years. If you plan to keep it very long I would look at a IIXL or E-90.
