I can't speak for the gun market in OK, but here in WV you'd be lucky to get $450 out of it. They are at the gun shows all the time, and for the life of me, I can't figure out why people don't want to pay anything for them. A stainless one will sell now and then, but overall the 595/695's don't sell well at all here. They're fantastic guns, I've had several and have yet to have one that didn't shoot like a laser. If I wanted a cheap deer rifle, I'd hit the gun shows and haggle one down, I'm sure I could get one for $400 and probably less. The last 595 at the local shop was practically given away, because it had set there for so long. It was a sporter 22/250, blue/syn, and that had a lot to do with it's lack of popularity, but still they just don't seem to sell.
Now the T3, that's a whole different ball game. You can't keep them in stock. Believe me, I have two of them right now.
