I am a tech dinosaur, sorry. I like using my 788 and for years have wanted to get a compatible cd drive for it. I have just acquired this tascam cd drive which seems to be the same guts as the Tascam CD-W512S. The manual says to only use teac blank discs; hmm, not many of those about. Any suggestions for discs that will work okay and are available greatly appreciated, especially if you have used them yourself. I'm thinking slow speed re-write, ideally 1-4x, max speed 10x.
