Nice find, and that's a good price.
One caution: Those are collectible. Don't change it by shortening the barrel, installing the DSA top cover that requires drilling into the receiver, etc. As long as the only mods you do can be switched back to original configuration you'll retain the value if you decide you want to sell it sometime in the future.
Just thought I'd mention it cause I know some guys like to start customizing any new rifle. If you want a FAL to customize and tweak to your heart's content, there are plenty of cheaper ones out there with no real collector value for that.
