I was in the market for a replacement bowl for my old Cuise, and ended up getting a lightly used Cuise thrown in along with it. 
I'm being facetious, of course, but not as much as you might think. Somebody on a local buy-sell page was selling said Cuisinart after splurging on a Robocoupe, and I got the whole shooting match (plus a tolerably full set of discs) for what a replacement bowl would have cost me on eBay.
ETA: The original point I was working toward is that these things are pretty durable, so (as Jo said above) buying a machine to match your accessories, even if used or refurbished, isn't necessarily a bad move.
