I bought 10 TDK SA-X tapes called SA-X Limited off ebay for a real good price and would like to know if anyone know's what the difference is between the regular TDK SA-X and the TDK SA-X Limited cassette's?I like the SA-X tape but was wondering what TDK did to the SA-X to make it Limited?Thanks for any info anyone can give me on this..Thanks,Keith H..

First I've heard of a TDK SA-X Ltd.

Ltd. edition packaging ?
It's not likely they would changed the formulation for a limited run.

And watchout for that TDK eating Sony tape deck of yours.
It may try to sneak a snack...

;)

cheers
