Strictly speaking, this isn't an exercise machine, but it occured to me while I was working out today that I do have home equipment, and that might relevant to your question.

I bought expensive (but high-quality, durable and comfortable to use) free weights 18(!!??!) years ago. (Holy crap, my weights can vote.) I bought a padded, inclineable weight bench 8? or so years ago. Still using both of them. Pig iron.
