Well I have a VZ58 and it's fun, plus it goes bang every time.
I got from Milarm for like $375, $437 all in all. Not bad
Mine came in typical surplus condition (some minor paint rubbed off, nothing serious) and the "wood" can use a coat of clear if you want a mirror finish.
The trigger is smooth, to me anyway, much better than an SKS.
Sights will need adjustment since they are sighted in for 800m :shock:
As for cost of ammunition, 7.62x39mm Czech surplus can be had for $169 per 1120 rounds, that includes shipping but add about $12 for taxes.
I suggest the modern military muzzle brake that Marstar sells for $40.
It minimizes turbulent gases for improved accuracy.
The grip IMHO is small, but you can adapt one made of wood for an AK.
That's about it for now, I intend on getting a folding stock soon and more mags.
Hope this helps.
