When I was in the market for an 8mm, M-48As were all over so I bought one.
I couldn't be happier with it. My only complaint, and it's a minor one, is the arched bolt. I've never really been the biggest fan of straight bolts and greatly prefer bent bolts (not saying they're better, just that I prefer them). The somewhat-bent-but-not-quite bolt would be my only sticking point. Otherwise, it's a wonderful rifle.
Every now and then I'll see a K98 on GunBroker. It's only a matter of time before I buy one.
