Midnight Rambler,
it doesnt matter now if it's "100% certified" or "certified plus" as TDK mainly labels everything 100% certified now. what really matters is where they are made in.
the ones made in taiwan are made by ritek; therefore, they are crap.
the ones made in japan are made by taiyo yuden; therefore, they are excellent.
last time i checked, compusa was selling both kinds. just read the fine print and look for "made in japan"
