My wife has 3 mechanical keyboards, all equally or more expensive than mine. She thinks Click Clack skulls are "cute" so she stole my only one to use on one of her boards. Fine with me.
My brother is a by-night metal scrapper so he brings be home old pc stuff when he gets it to check it out before it goes to the recycling/ecycling place. He also has hooked me up with people who work at the e-cycler who hold old stacks of keyboards for me to look at once a month or so.
None of my friends are true computer nerds. One is a mechanical engineer and and does video editing as a hobby, so I am trying to get him involved in mech keyboards as he is in front of a computer most of his waking hours.
