I have had three of them. One in 30-40, one in 7.62 Russian, and one in .405 Win.
The first two were originals in so-so shape, I eventually traded them off. The .405 is one of the new release (made in Japan) guns that I bought just a few years ago.
I haven't kept up with the collectors market, but 5 grand sounds a little steep even for an original unless it is in like new condition.
Wish I still had the Krag, but if I was going to do it all over again I would find a .405 and never look back.
