Yeah good point. I agree, the 19's probably not B-Die. Also agree with the Micron E-Dies, solid stuff at a decent price. The 3200's clock really well. I don't think I've seen Ballistix Sport LT for awhile though, not sure they still sell them. They were the sticks with the E-Die, and they only officially came in 3200 *I think* but just change the frequency to 3600, no other changes at all, and they ate it for lunch. Not sure what chips are in the Ballistix Elite but I don't think they are E-Die. Still pretty good value though.
