You can find CETMEs on line now for $499+ shipping. Dealer price is cheaper. The price has come down a lot in recent months due to the glut of ARs on the market. With a decent scope mounted it might be worth $550.
Forget match grade, it is unlikely that Century would make anything worthy of the name. These are "rebuilds" of the Spanish version of the FAL, which was a very good design for a battle rifle.... 60 years ago. Jamming and feeding problems can be overcome and a good FAL specialty forum can assist you should you encounter problems.
