Voyager Series: How "rare" are they, really?

[BarryT]

Hi all,
. Curious about the Voyager Series, (specifically... but the rest of the HP calcs as well), and if anyone knows exactly how 'rare' some of them are? Mainly... do the levels of difficulty listed in the "Collectors Corner" of MoHPC still hold water, or are they in need of over-haul?

. I'm not sure how old those are estimates are, so I can see some of them needing to be updated... in both directions. As more people discover things they have stuck away, and, as access to the net has become even more widespread than when the list was compiled... I can see an influx of calculators becoming available 'online'. Then again... for some, I can see that time has made them more rare as well.

. Anyway... just thought I'd see what the thoughts are from the experts here in HP-land

Thanks everyone.
