Hi ScottL: Hmmm. I checked the Musitronics website and found no mention of a hard drive specificly for the PSR2000. Nevertheless, I'm hopefully anxious to find out what you hear from them, cause outfitting the PSR2000 with an internal hard drive (and at $160) sounds almost to good to be true. The only real complaint I've had about the PSR2000 is the lack of a hard drive, so if this can be solved, this would be a FAR more economical route than upgrading to the Tyros, and with the 2000, you get the great sounding built speakers, with the Tyros you don't. - Scottyee
