I would guess most people here are aware of how to use ebay to suggest
(mostly inflated) pricing. In the past, I have used Hammertap and
Terapeak, but they both seem to have gone away. That said, I finally bit
the bullet and joined Worthpoint. So far it is the best I have used and
at this point highly recommend it . The format is similar to Ebay BUT...
it goes back in time much farther than anything else I've used. The
farthest back I've seen so far is 2016. It even shows the one Intel MDS
system Scott (?) posted about that sold for $500 about 1 year ago in
July 2023.
The pricing is comparable with the other services I've used at about
$30/month for the basic searching ability (all I am interested in.).
IMNSHO, it is well worth it as in addition to past pricing, it also goes
back farther than anything I've used previously.
My opinion, it is the best I've seen for looking up past ebay sales.
