Just trying to find going prices on NIB SP89's and if there are any good deals out there, cant find to many on GB or Guns America

NIB SP89's are low to mid $4k, used ones are mid to high $3k. Both depend on what the seller is offering with it (mags, slings, spare parts.. etc) and how proud he is of his firearm. I picked up a used one for $3300 and promptly spent another $900 for a rebarrel and refinish. The one thing I learned when looking for mine, is to have cash in hand because they move pretty quick. Keep looking on GB and also try subguns.com or sturmgewehr.com or post a "Want to Buy" ad on HKPro.com. Good luck!!
