I set a search on Craigslist for the things I want and they e mail me all the latest additions every day. I like Royal vacuums so I have a search for them and that's how I found a free top of the line Starks/Royal 5700 upright, and my 4650 Canister for 25 bucks. I get a lot of hits for Kirbys as well because they are so similar and there always are some of those too from dirt cheap to ridiculously expensive but they are out there. I don't see too many of the newest generations but it happens and if you find one you like jump on it quickly like I did when I found the 5700. He didn't list a price so I e mailed him and he said free of course and comes with extra bags and belts so I beat feet to his luckily reasonably close by house. He was happy a vacuum nut wanted it and would actually use it as he liked it a lot but they had just put down wood floors and had no use for it anymore.
You might also want to check out nextdoor.com as it is a local neighborhood type site that lets your neighbors keep up on anything local happening and they have a ads section for free and for sale items that can have quite a few cool free and cheap things in it.
