I had very seriously contemplated buying second hand Josephs and decided I couldn't do it at this time, financially and for some other reasons. Just really bad timing for me.
To take the sting out, some part of my rationalization was also adding up the cost of buying used, shipping, then shipping to JA, updating....and the cost getting ever closer to a new pair of the JA 2 speakers. JA speakers are such eye-candy "audio jewelry" in terms of build quality and looks I do like the idea of buying pristine new speakers.
That said, I can see why it would also make sense to grab a pair of original perspectives second hand. They are amazing speakers as they are, you get them much cheaper then new, then if you find you really love them later on when finances permit you can have the updated to the new version.
So, I can spin the idea of buying used or new either way. But if you don't absolutely need the latest update right away and like the idea of getting a JA speaker for less money, second hand sure seems to make a lot of sense if you can find them.
