The newest burner actually shipping would be the Pioneer 109, and there has been quite a bit of trouble with that drive. I wouldn't recommend one until (a) the firmware matures and (b) the software catches up. Immediately preceding that would be the LG-4163B, which seems to be a quite solid drive. It does not allow much (if any) overspeeding, there are no hacked firmwares, and the interest here on cdfreaks is rather limited -- probably becuase of no hacked firmware and no overspeeding? But the people who have the drive ALL appear to like it.
