Maybe you can think of the Plextor PX-716AL as a professional CATS-like scanner bought at a consumer PC drive price. Some people have said Plextor drives are the closest things to professional scanning devices. (Not that I agree with that.)
It's sad that it still doesn't have IEEE 1394, USB 2.0, SATA, slot-loading, DVD-RAM, etc. all in one body even for so much.
