i just bought a used Casio Cdp-220r for $100, and the worst feature of it is it's piano sample. So, it's got a mic in which plays whatever you plug in to it's speakers. This means, I can plug in the midi to the sampler box, load a better piano sample, have local keys off, and plug it back in the mic in. I'm effectively bypassing the piano's own computer. I love it!
