Top three calculators ?

[BusyCalc]

My personal list of the top three calculators is

1) HP45 at work. (Bought an used one, not very convinced, but now I love it very much and I use it almost everyday at work.)

2) HP65 at home. (Inherited from my father, who used it at work in the 70s/80s. Its condition was pretty good, except the famous gummy wheel. I restored it and since then it started my addiction to the classic HPs. I introduce a card once a month, only to hear that amazing sound and see the numbers dazzle. It's like having a Rolls Royce and going for a spin just for fun.)

3) HP80 at home. (Similar to the HP45, but I like to use it at home for the household matters.)
