If you have some patience, shop around. I see a Browning Gold 10 used occasionally going for a good price. Some people get them and then decide a 10 isn't for them. It is a limited market.
Another note. As I said I replaced a lot of parts in quite a few Ithacas; I was a dealer back then. I do not know what the parts situation is, but they have been out of production for a while now, so whatever is left has to be shrinking.
