Calculators you regret not buying?

They sold at around 300 german marks, which would be 150 Euros now. Occasionally, unassembled kits pop up at eBay now for around 2000 Euros. If I only I had been born with the gift of clairvoyancy it would be me who builds Mars rockets and not Elon Musk ;-)

I guess the comparable item on this side of the Atlantic would be Altair computers, or similar S-100 machines that came in kit form. And some of the factory assembled consumer oriented 'appliance machines' for those that didn't know which end of a soldering iron to hold are commanding high prices as well.

And let's not forget collectible comics! Pennies back then. Thousands to millions of dollars today. Incredible.
If I only had a box full of Action Comics #1 ....
