Used for practice
The sounds aren't the best (as expected), but it's pretty good for playing out ideas in my head and practicing piano. I'd use it as a MIDI controller...if I actually had a MIDI interface :P Probably gonna trade it into Guitar Center along with my LPD8

I got this for $18.00 at Good Will

It's ok
I mean, it's kinda old. The keys aren't weighted, and no pitch bend or modulation for vibrato, no arpeggiator.
