On different occasions last year, I bought three Kirbys at Goodwill--a Legend II ($10), Gsix ($20) and G4 ($25). In each instance, used the rationale that it was worth more in parts than I was paying for the whole machine; in fact, the Gsix, which was in the roughest shape, was bought specifically for parts to fix up the G4. Too bad I couldn't keep to that. A few months later, I ended up feeling sorry for it sitting in pieces, and scrounged up enough parts to fix it up, mainly from what I had on hand. The big parts purchase was a G4 that was flying under the radar on eBay, which was able to get on the cheap. At a glance, you can hardly tell the difference, other than it being charcoal gray instead of black, and having no flecks of yellow.
