Cherokee 235 vs Trinidad vs Comanche

Hello, All!

About a year ago, I started airplane shopping. For personal and
professional reasons, I had to back-burner that after never getting past the
tire-kicking stage. Along the way, I got a lot of help from folks on this
board, so now I'm returning to the fount as I prepare to begin anew.

Last time around, I'd focused my energies on the Piper Comanche
(PA-24-260B/C). The combination of useful load and ceiling/climb
performance (I live in Colorado Springs, w/ DA in the 10K'+ range in the
summer) were the main factors in that. After some looking around (then and
now), I have some questions (seeking opinions) on two other marques:

The Socata Trinidad (TB-20) seems to pretty closely match or slightly exceed
the Comanche's performance numbers. For a comparably equipped Comanche,
they seem to cost (acquisition) about the same. Meanwhile, the Trinidad is
a 20-year-younger airplane, with cheaper insurance and (I'm given to
believe) cheaper maintenance due to (a) ease of access and (b) availability
of parts. Plus, the gull-wing doors are appealing to me (ease of
entry/exit, not to mention "cool factor"). Can anyone weigh in here, either
to confirm these observations or to squash my newbie analysis? Other
thoughts?

The Piper Cherokee 235/Charger/Pathfinder (PA-28-235) [and I can't figure
out if the Dakota (PA-28-236) is an evolution or complete change of the
line?] is also attractive. I'm not hung up retractable gear (indeed, if the
maintenance is cheaper without a correspondingly higher fuel burn, I'm all
for fixed gear), the useful load numbers on the 235 match the other two, and
they can be had somewhat cheaper (acquisition, insurance, and maintenance)
than the other two. I'm concerned mostly about ceiling/climb issues--how
will this airplane handle my high-elevation location? Same deal as last
paragraph: can anyone confirm/deny these thoughts? Other thoughts?

Thanks--I'm a newbie, I know it, and this board has been invaluable.
