I'm of the generation that missed out on slide rules by a decade or so. My parents had one thta i played with as a kid, and I learned to do multiplicication and division with it.
I'd like to get one now, mainly for fun, but if you want to buy one on Ebay in good condition, you have to pay quite a bit of money.
Since this is something I want to keep on my desk, not only for decoration but for actually copute things if I'm bored, I really want tone of the nicer ones.
Seems to me that this is also a lovely use for a desktop laser cutter. Dig out a copy of Pynomo or something and make your own scales that suit whatever specialty application you have in mind.
