Me thinks go water cooled for used. Should have held up a bit better
than air cooled radials.

Since just about all aero engines are air-cooled, the choices amongst
water-cooled are pretty slim --especially since few water-cooled are
conversions od auto engines and have little track record in aviation.

What radials? The OP is asking about the usual horizontally-opposed
air-cooled engines, Lycomings or Continentals.

All I know is that used aircraft prices generally remain dismal, so I
assume used engines prices remain low too. Look in Trade-a-Plan or
Barnstormers. As to quality, beats me, that's why I got a new engine for
my RV-9A.
