I flew one that was given to me NIB by a relative as a gift, back in the mid '80's. Great flying airplane it was, with an OS .61 FSR. I flew the bejeezus out of it, and sold it to another flyer who spruced it up and also flew the bejeezus out of it.

I have seen a couple for sale on the 'Bay in the last few months, but they command some steep prices. Good luck with your search.
