Look at AIM, SOG, etc. for Yugo M48s, Yugo M48As, Yugo 98ks, Yugo 24/47s, Russian Capture 98ks, German 98ks, and Czech VZ24s. Those are the best condition 8mm Mauser rifles.
The Turks are usually beat to crap and most of us buy them to sporterize. The Argentine, Chilean, Spanish and Mexican Mausers are tough to find in good condition. There are a lot of variations among the different year models.
If you want a German 98k but can't afford the price the Yugo 98k is a very good buy. The Yugoslavians took a lot of German 98ks as war reparations, ground off the Nazi markings, rearsenalled the rifles, and stamped the Yugo coat of arms on the receiver. They were then issued to their troops and are usually in good shape.
The M48s are an intermediate length action 8mm Mauser. The parts don't interchange with the 98ks but are usually in much better shape.
You do know that you can't have just one- right?
