With my collection I like to focus on the unusual, unique, or weird. A gold plated Kirby definitely falls under that category, for sure.
I do add some good well regarded vacuum models here and there, and of course any vacuums I rescue from the curb or thrift stores for cheap are more than welcome to live with me. It actually ends up being a nicely balanced collection with all those combined factors and "rules" in place, so to say. But in a do-or-die moment, if it came down to the wire and a bad situation, I'd really only keep all my Kirbys. And my Zed-Series Hoovers. The rest would move on to new caretakers. But hopefully that won't happen until the planet looks like "Futurama" perhaps. lol
