Classifieds scams?

[naddy]

What do we know about scams targeting potential buyers of classic HP calculators?

You'd think scams would involve iPhones or such, and vintage HP calculators are way too niche, but I'm starting to get suspicious. For the past few weeks, I've been watching eBay and Kleinanzeigen (Germany) for HP Pioneer models. Yesterday, an offer for an HP-42S popped up where the images seemed familiar, but I wasn't sure where and if I'd really seen them before. Today a different offer for an HP-42S popped up on Kleinanzeigen that was clearly copied from a running offer on eBay, seller in a different country, different price. Whatever the details, this one has to be a scam. (I reported the offer as suspicious and Kleinanzeigen removed it within minutes.)

Watch out!

PS: That earlier offer from yesterday is also copied, I found the original on eBay again.
