There was a real vintage one for sale on CGN along with an M16A1 (yes, full auto prohibited) and I think it in the $2500 range (but $12,000 for the gun).
Try the Canadian NV retailers and see what they have, Sometimes a repro using Russian tubes or perhaps a rebuilt unit. Importing should be the last resort. I would suspect that even a Gen 1 would be stopped and refused export, based on fear or ignorance of the U.S. Customs officer who has it land on his desk.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
