The values of some 'better' planes have collapsed in the last year or so however.
Somebody in the USA is now selling a TB21 for $90k. S/N 559, 1986 so younger than the average old can in the UK, 1780hrs on the motor so close to OH (which would cost about $60k) but avionics probably OK.
Owning outright is wonderful and that's what I do, and have often posted a list of the great reasons, but if you can assemble a group of decent reliable honest people that is better because it reduces costs. It is just really hard to find those people, especially in the GA game where almost everybody talks the talk but few walk the walk.
