For real historical interest, I'd go with the K98. It likely saw action during WWII. The M48 was post war, and was probably laid up in storeage it's entire life. The M48 may look better for this reason, but it just doesn't have the history behind it. Actually, both are good rifles, I'd get both!
I'd go with the K98, this will have the model 98 on the rail and I have heard some people who have gotten these types with some of the German markings on them. Where did you catch the advertisement from CDNN? Whenever I check the web site I never see these rifles advertised.
