Those are pretty enduring in popularity, they shouldn't be too hard to find.

For under $200 though? Only if you are an airsoft nut. Not for the real deal or any replica I know of.

Your best bet would be to hit the gun shows in your area. The "Gun, Knife, and Military" expos are great sources, but you have to watch out because some morons will overcharge because "it's military" or "this particular unit killed 327 Nazis" or whatever yarn they spin to make you pay more. Take a knowledgeable person with you to sort through the deals and the garbage, but I have yet to visit a gun show that didn't have one or both of those weapons available from private collectors.

I saw one today gun shopping, don't know if it was replica or not, but it was over 500 I think.

I doubt you will get one for under 200, maybe a broken piece of garbage one, but not a functioning one atleast.
