I got a really really rough SKS during the height of the panic, paid about $350 for it. I ruined the stock when I cleaned it and ended up with just spray painting the entire thing. It is a shooter, as in, it shoots. It's not for looks at all. Sometimes I see really pristine SKSs and I am jealous. It might be worth it to pay more for a gun that really looks super nice.
Sand it down and refinish it.
