Price range for a HP 41cx

[Leviset]

I’ve seen some ridiculous (presumably a dealer?) prices - highest was £750!
I bought my HP-41CX 3 years ago from a guy in Harrogate for £45. It had never been used bought as a backup to his work one in Singapore. I believe he turned down X4 £45 from dealers as he wanted it to go to someone who knew how incredible they are. He was slowly going blind with MD and moving into sheltered care after a lifetime in the Oil Industry. Some kind people in the HPCC (you know who you are!) gave me lots of bits and pieces accessories including a card reader and printer. I also got one of the HEPAX modules from Diego that allows you to put a number of modules onto just one as I see people asking £150+ just for a single module.
I also bought the DM41L from SwissMicro which is an awesome modern version of the
HP-41CX. You probably know about the i41cx+ app which must be the best software emulation I’ve seen of the real thing. I think the same programmer does the HP-67/97 apps as well. I’m still looking for an HP-97 as it was the very first programmable Calculator I wrote software for - I did buy an HP-97 from eBay for £130 but it turned out to a total dud, a number of electronics friends tried to get it working to no avail and I believe it’s now in the Museum of The University of Valencia (long story!).
My next door neighbour is retiring and moving and has given me every electronic gadget he’s ever bought since the 80s so the 3 calculators I don’t have or can’t afford - the HP-97, HP-42C and the HP-35 are each running as apps on 3 separate iPhone 3s!
