I think there are a lot of us, but we aren't very visible because we just buy some best-bang-for-the-buck equipment to get us above trash-tier sound, or hit a few pawn shops, get set up to our satisfaction, then don't think about it again. Shit lasts decades, once you hit good-enough there's not much reason to keep messing with it. Only thing you might be replacing about once a decade is headphones—maybe.
