Looks like out of the two threads this is the one that lived, so I'll copy/paste my response from the other thread...
I know some people who have done this and got burned badly on the condition of the machines. He resorted to selling them off on eBay to recoup what he could, but he essentially took a huge hit and the gamble never paid off.
It used to be that buying in bulk out of Europe was a good way to get nice pins, but a lot of the nice re-imports already made their way here. I'm not saying that it's impossible to get a good lot, but it's less likely than it was 10 years ago.
