Good question. Unless you personally know the previous owner how would you know the Utopias are still in good shape? Personally I would only buy used factory refurb or used at an authorized dealer.
LOL! You really did make me laugh with this and prior posting. Thanks. Good to see I'm not the only one that occasionally needs to backtrack on my postings.
As for the poll above, I think it shows one thing quite clearly. Very few people with Utiopia's answered the poll. It also
might show that very few people with Utopia's even read this thread.
FWIW, I completely agree with
@bflat. I would only recommend buying an open box from Moon, a new one from an authorized dealer (work with them, bet you can get a price just a little more than used ones sell for here), or one from a friend that purchased new from an authorized dealer and that is willing to return it to the dealer if there is an issue.
While we do not know the failure rates, they certainly were high enough in the beginning to be troublesome (as Jason said earlier) at that time. If I were buying used, I would ask for the serial number, and try to determine if that we a relatively new unit. What would scare me the most is a "new in the box" Utopia from a non-authorized dealer, or a person on a For Sale forum. Generally, electronics fail early in their lifetime, so if the item is DOA or mildly defective and you can't return it, your are SOL. If you get it from a trustworthy person that has used it gently and knows it works properly, then you have a much better chance of success.
