Calculators you regret not buying?

Buying a calculator to see it's value increase would have been an actual waste of money.

This is an often overlooked point in discussions regarding the "increasing" value of calculators and other collectibles. The $150 or so that a 42S cost in 1988, properly invested, would be worth many times the cost of a mint condition 42S on fleabay.

OTOH, I do regret not buying several 50g's when Best Buy was selling them for $60 each in the early teens. They appreciated greatly soon after. Such is the nature of 20/20 hindsight...
