This is an incredibly versatile instrument - I actually bought one of these (the FA-07). The sounds are superb and the recording functions are quick and fairly easy to understand. You can also connect up to a DAW easily without the need for an external audio interface - which I like.
The FA-06 and 07 both have synth action keybeds and the 08 has a graded hammer action bed. I chose the 07 because I wanted this as a top level board with a piano action board below. But I must warn you that the keybed on the 06 is not good, the 07 is much better. The FA-08 weighted keybed I found to be quite nice, but there are others that I prefer.
