If you want it now, you're going to overpay. I don't believe they will hold value like the czechpoint guns will, but even those are inflated right now. Get on a list and buy a czechpoint gun if you really want a vz58 because you probably won't find a vz2008 for significantly less - the market is just crazy.
Personally, I don't think the vz is worth more than 1500, and that's stretching it. Don't get me wrong, I really like mine, but I got it new at around 1,100 before the craziness and I bought the NOS mags before the gun at 12 to 14 dollars a piece.
I would say be patient, prices will come down some. Remember Sandy Hook or when Obama first got elected? We are in a bubble and it will pop.
