Neither of mine have had the "gremlin". I bought my restricted from Marstar when they were $599, and my non restricted from Canadian tire for $899 four years ago. Excellent rifles. Will never sell them. There's a great amount of aftermarket parts, so you can really make it how you like it. The must haves in my opinion are the bolt release extension, larger pistol grip, and the extended mag release. I can definitely see these rifles as ones that you'll hear people moaning about not getting when they could. Since 2006 they've doubled in price and are still worth it to me.
Don't go the route of building up an SKS instead if this is what you want. An sks is a great rifle, but a vz, it is not. Fighting, filing, and fumbling is the tapco path. Do your self a favour.
