I am also a long time 41cx owner/user, and have been watching eBay because I have recently bought some new goodies for my calc (thanks to those of you who sold to me, I've had good luck with everything so far).
It looks like what was going for $80-120 two weeks ago is going for $200-400 now. Several of the calcs appear to be from sellers who don't appear to have the background to answer questions about the history/functionality of the calcs.
If you look closely, two bidders are running the prices up on these. They have very little history with eBay. One of them is into HP calcs about $1400 this week as high bidder or final bidder on 3 41CXs, 3 41CVs, and 1 ROM module. I sincerely hope the buyer and sellers end up satisfied. Wonder if this buyer knows something about these calculators that I don't. Is HP suddenly buying all existing calcs up??? :)
The other bidder appears to be bidding from Italy. He has run price up on 5 calcs, then withdrew from three of the auctions, was outbid (by other bidder above) on one, and on the one he was high bidder on has not responded to seller and got negative feedback.
Don't know quite what to make of it, but I'm glad I'm not in the middle of it...
Hope I haven't offended anyone with these observations.
