Hey I don't know about the MT prices. You'll only get what someone is willing to pay. Me I think the 98's and earlier were the best built MT's especially in the ats34 steel. The SOCOM is the defacto s.d. knife if you ask me. Good sweeping belly, very pointed but strong, lock up is superb at least on the ones I have and have owned, opens like butter and are beyond sharp as one likes to say. I even have the lanyard attached and I hate lanyards except on whopper choppers.
Now I also have an old MOD Tempest. You know the one kraton inserts and it rivals the MT I own for quality. Doesn't open quite as smooth but the ergo's on this little knife are excellant too. I think out side of a sebbie the MT's and the MOD's old school are about as good as you can get when it comes to build quality. You just don't seem to loose money on them. keepem sharp
