K98s are great guns.
I've been very happy with what I've gotten from SOG.
With both of those things said, be aware of what you are getting:
1. These will be non-matching rifles
2. They will be Russian Captures
3. They will be import marked
4. They will be missing front site hoods, cleaning rod, sling, and capture screws
I think they are good rifles for a good price. They will never be true collector K98s though. If you want a rifle that will have more collector value in years to come, you are better off getting a Finn M39.
