The Ithacas and the Smiths are still decent buys. All the others, in anything other than 12ga, are pretty pricey. And you have to go with an American 16 to get something close to the "game gun" feel you get with a Brit 12, or many European 12's for that matter. Then all you have to do is deal with the short, often dog-legged stock.
I just swapped a very nice NID 16. Decent dimensions, got about $1100 on it as part of a trade--which means the gun shop will probably sell it for $15-1600. I'm happy because I made money on it, and the Merkel 12 for which I traded weighs almost exactly the same as the Ithaca 16.
