I've seen people part out vacuums - I've never done it. I just picked up a Dyson at an estate sale for $10.00. It was marked with $20 and a sign that said "does not spin" I made an effort to seem interested in it and walked away. The guy at the checkout table said, "it works, it sucks, the thing at the bottom just doesn't spin." i told him i just saw a video of a guy parting them out, but I'm not so sure i want to take the risk at $20. He came back at me, "wanna take the risk at $10." I bought it right up. I was actually willing to at $20, but wanted to see if my tactic worked. I should be able to part it out at around $150.00.
