    Re: recommendation for slide rule ?

         You have succeeded in getting me interested in slide rules. I
    have never owned or used one but after some internet research I see
    that they have been to the moon and back. Now I will have to get one!
    So far I am leaning toward the purchase of a Pickett N3-ES which is of
    aluminum construction. The slide rule could very well be the pinnacle
    of low tech achievement. Right there with the mechanical chronometer.
