I picked up an all matching good condition Chileanicon for about $100 in the US last summer. Stock looked horrible, very dark black and kind of gooey. Cleaned it up and found all the stock markings intact. I'd say average price for a decent looking functional rifle with a good bore is about $200 but I've seen them as high as $300. I got a really good deal on mine, they wanted to get rid of it plus it just looked bad.

Ammo is a little difficult to find and a bit more expensive than some of the other milsurp calibers but it's not terrible, depends where you buy it. Cabela's sells it for about $25 a box, Bass Pro Shops about $35 a box (same type). My local gunshops if they get it are somewhere in the middle.

Dunhams sells them periodically. Their regular price is a bit over $200 if I remember correctly. I don't know if they put these on sale, haven't seen them in their flyers.
