Dale,
Zach Grant is soon to be next ICS Pres and has a turbo today - his comments are somewhere on this site, perhaps if you search.... Anyway, the last time he posted on this he told a guy he wouldn't buy a turbo unless is was an absolute requirement. He said he can afford it because he does most of his own maintenance.
I share this not to dissuade you but so you aren't surprised later. My 39 is not turbo and before it got obnoxiously expensive, we used to fly into Aspen all the time. We just did a lot of planning, flew the passes, only VFR and in the mornings as far as possible. If you want to go over the Rockies, I would be partial to a turbo too.
If you want a pre-buy in AR, then Cliff Wilewski from Heritage Aero Rockford, IL or Tim Talley from Clifton Aero in TX or Zach Grant from IN. All phone numbers are in Pathfinder
