I had i30 for several years. It has a big touch screen although it's rarely used.

Sounds are OK - not awfully great IMO.
Electric pianos are not great.

Rhythm/styles: Good drums. I rarely used the accompaniment because I play manual bass and just use the drum rhythms.

Plus: It has sliders to adjust volume of individual parts. Looks very professional.

Drawback: HEAVY !! This thing is built like a tank with metal case. The fill-in buttton got misaligned recently.

Recomendations: All I can say is that lots of people like it. But I personally just give it a 7 from scale of 1 to 10.
