FWIW
as far as EKI QC, i have bought about 7 the last 2 yrs (SOCFK,CQC8,I&I tanto,P-Tac,spec war,commander and CQC7) and the only one w/any probs, was, well the CQC7, poor lock up - BUT a trip to EKI solved that and its fine now also. i just might be lucky, but have not had any probs w/ EKI's, the prob w/the '7 was minor, if i wasnt so picky i wouldnt have even bothered w/it. imho EKI is one of the better makers, at LEAST on par w/BM, and BM is imho pretty damned good.
also have a BM 975S-bt and its been a winner also, bought it used for $60 (barely used) and have worked it pretty hard and its held up fine, but cant say its better than the EKI. i would say probably equal though. i do like a lot of the EKI designs better than the BM, i really wouldnt get a CQC7 would rather have a SOCFK, but i think right now they are kinda hard to get.
really ya cant lose, either is fine, buy the one that "grabs" ya
