What should be my next LED HP calculator?

[Namir]

I suggest the HP-55. I t was my first calculator love!!! Despite its rather limited programming steps (which I learned to use to the last step in calculating all kinds of series-based functions) it has twenty registers, a stop watch, and a wealth of math/stat functions. I chose it in 1975 because where I lived in the Middle East there was no HP office to repair calculators (there was an HP office though to sell computers to the local government). I was looking at the HP-65 but feared the failure of the card reader, so I chose the HP-55 where I can access all that functionality by simply turning on the calculator.
