Availability of used aircraft for sale seems a good indicator of how
well owners like living with a particular airplane...

Not really. The statistical fluctuations are too high due to the
small number of aircraft built. Right now there are no Russias for
sale in the US, a little while back there were a whole bunch. Not
long ago there were a bunch of ASW20s on the market, I don't think
that's an indication that ASW20 owners are dissatisfied.

I think a better indicator is the number of hours on the ones that do
go up for sale. If they are racking up a high average number of hours
per year, their owners are probably quite happy with them. If you see
them going for sale with like 5 or 10 hours per year on them, then
maybe not so.
