Surprisingly, the Korg I30 lost its price fairly quickly of it being released, at least in the UK anyway. I do not think they sold that well to be honest, which perhaps did not give it much justice as I think it has some inspirational styles, some even better than the Solton's.
But for me anyway, its just the average sounds, rough midi playback & generally poor user interface (or operating system) that let it down for me, not to mention it lack of amplification. Had all these been improved, then it would of been a killer machine for sure!
But like I said, its still a great keyboard and I loved it when I had it.
