I finally succumbed to eBay and signed up a week or so ago.
Now I have acquired, among others, these nice classics: HP-11C, HP-32S, HP-32SII, HP-42S, HP-48GX. These will join my stable of HP-12C Platinum, HP-15C LE, HP-16C, HP-30B, HP-35S, WP-34S, HP-48G, HP-49G+, HP-50G.
Still a few bids going on, might end up having some duplicates, and hope to win an HP-33S. For some reason the HP-10C and HP-15C are hard to get at a reasonable price. The HP-42S I found here in Europe, did not have to pay the exorbitant $300 American price.
I am also adding a Sharp EL-506A to my collection, and hopefully the programmable EL-512, too. I have two EL-5103s since my student days. The Sharps are great calculators, too, in their own way.
I will need to do a lot of calculating to justify all this computing power.
Thanks, eBay, for ruining my credit position...
