Another guy in the "FN FAL, HK G3, or M1A" thread just bought an STG-58 from century, which is essentially the same gun, for $700 including gun, 10 mags, bipod, tax, ffl fees, etc. That seems like a pretty good deal. It also had an Imbel receiver. The Springfield Armory stuff, IMO, is a better made rifle though, so I's say maybe $750-$900 for the gun itself. Just a ballpark guess though....
