I've had the experience where people agree to buy my broken computers for parts and the deal is done, until I mention that the "drives are wiped and ready to go". Then I never hear from them again. Granted, somehow visiting the craigslist site turns ordinary people into flakes, but the "wiped" statement correlates a bit too well with the vanishing interest.
