Yamaha PSS-130
Yamaha PSS-130 - I paid more for this than I would've liked, especially given the condition of the button membrane, but it's not a bad little keyboard. There's nothing especially fantastic about the sounds, but you can program little melodies into it which play back with any of the built-in rhythms you'd care to choose. You can't bypass the rhythm (without modifying the circuitry), but it's not a big deal.
