I've purchased three halfway decent A-65s for an average of $1500,
each, on Barnstormers, within the last six months. One of them was
"good to go" as an experimental, and two of them would require about
$4000 to make them good, serviceable CERTIFIED with complete logbooks
aircraft engines.

The fact that some people lack the ability to scrounge, and keep eyes
open and cash ready, doesn't mean that the rest of us cannot.

The cost of the auto conversions, especially the "kits" just doesn't
justify the risk involved. If they were truly less expensive, I'd be
all over them. Unfortunately, they cost about the same, or more, than
buying more proven aircraft power.
