I'd add my two cents to some of the other posters: really fine condition Kar98k German Mausers are in very short supply, partly because so many have been ripped apart to serve as the base for a 'deer rifle'. When you can buy a new, purpose-built American-made bolt action sporter for around $400, there is no excuse for destroying a collectors' item, which is what these WW2 guns will become as their numbers dwindle.
As others have posted, if you check the gun auctions online or gun shows, you will find plenty of German-made '98s made up into sporters for very modest prices. If you feel the need to honor your German heritage, these are the guns to start with and modify to your needs. If you come across a really nice Kar98k, keep it as is and treasure it.
