I picked up one of these at Megamusic a couple of weeks ago and it's pretty awesome. It sounds good and it's pretty simple to use.
It has a few pre installed plugins. But you can also install Your own keyboard VST plugins. In fact thats the general idea behind the V machine. To load the VST pluggins into an external device to reduce the CPU usage. As well as using it live.
