You should have no reason to buy a 4160 today. If you want bitsetting in a LG drive
the 4163 is what you should have ordered. If you cannot get the 4163 and want the
bitsetting feature, then do not buy LG.
As for why the 5160 support bitsetting mentioned in the review, I am as clueless as
you are. Specially rigged batches of 4160 with external case? I don't know this one.
