Buy the 2-volume Airplane Buyer's Guide from Aviation Consumer. Well
worth the $75 or so considering how much you can lose with a bad
decision.

High level pros/cons of just about any older GA airplane currently
available.

For new, I'd consider the pressurized Columbia 400 or Lanceair IVP -
check out TAP for used models available. But now you're getting up in
the $$$$ price levels.
