I own the PSR2100. For $200 I purchased the HDM2, which is a flash drive you can install in the keyboard, and then it creates up to 170 virtual floppy drives. You can easily change banks during a performance to go to your next favorite midi or style.

Then I purchased a midi controlled sustain switch, so I still get three foot controllers.

I have downloaded all of the Tyros styles which sound great on my keyboard.

So I'm missing the feel, the megavoices, the live! drums, and the ease of a hard drive for storing registrations. You can get all of this for less than $1400, about $1000 less than a Tyros.
