Opinions on AOPA's Vref program please

I'm starting to narrow down my target aircraft and just today started
looking at them through Vref at the same time. I'd like to read your
opinions of that pricing service - both good and bad - and any
suggestions you might have as to other pricing tools that worked for
you.

BTW, the target will probably be something along the lines of the Cessna
172 / Beech Sierra or Sundowner / Grumman AA5. I like the Pipers also,
but want two doors - I've spent lots of time in the Commander 112
series, but don't have the budget for them.


Thanks.
