Yeah, I bought a m98 in 30-06 in a close out at a local gun store about a year ago. It was a great deal, but I was not in love with the gun- until I shot it. Oooh, that's one nice gun. I'm taking it hunting next season.
It is a field grade, not highly polished, but it is a deep and consistent finish. The barrel is 22 inches, and is fairly stiff. It is my second most accurate rifle (my Mark X in 270 is the undisputed leader).
They come with fully adjustable triggers and and are tapped for scope mounting. They are made by Zastava in Yugoslavia, which is a fine name in Mauser sport rifles, but they don't quite meet the finish standards of Zastava guns. Basically, they are very solid huning rifles, and nobody will out shoot you with it, in comparable calibers.
My only complaint was that she would not feed the first round from a full magazine. I had to use a file to knock a bit of metal off of the feed lips to allow it to feed from a full magazine reliably. The magazine was just a bit too tight, and the first round would tend to bind. My guess is that that not all rifles will have this problem, I just ended up on the left side of the bell curve.
If it is a good price, I would get it. You won't be ashamed of her, and she will serve you well for many years.
