Cindy got a dozen or so of them, new, about 6-8 years ago, and sold them for about $150.
I bought one and found that over a third of the rivets were broken, so it did need a bolt mod straight out of the box. Just keep that in mind as a possibility. Just because it has never come out of the box does not mean that it has been treated gently.
Not to rain on your parade, you still got a great deal!
