I purchased the Greywolf at the Tanner Show about two years ago.
I just happened across it and had wanted one for a while. The person selling it said he was selling it for another project. I got it for $1675 and it was in like new condition. It was very clean and stiff so I don't think it had shot very many rounds. It had no brass dings or scuffs around the ejection port. After shooting it this week I think I have the bugs worked out. The rifle is pretty heavy so if you can get one with the fluted barrel it may help with the weight.
I haven't seen many nice FALs around. Green Mountain Guns has consignments and you might want to check with them.
Does Atlantic Firearms have any thing? They have had some in the past. Good luck!
