Does anyone know where I can find this? Apparently it's so rare, it doesn't even have an entry at the VGMdb. Better yet, is the set any good, or would I be better off using unofficial game rips?

This was the version I downloaded. It's in bin/cue format so you'll have to mount the image file and rip it like you would a CD. It has all the music from Lufia 1/2/3.
