Kim, I had a E-600 for a while,at the same time I had a G1000 and a VA-7... The E lacked an EV-5 pedal input making it not as useable for me. The harmonizer and mic input with effects was useful, even better than trying to use a mic into the Variphrase for vocals[poor signal] on the VA. The lack of a Hard drive or Zip on the E is another reason I could not use it[ floppies are a poor choice on the job].. Overall the only one of the 3 that made sense for me is the G1000, better flexibility[ with buttons. pedals and sliders] and a zip system that allowed switching from sequence play to live play much easier..True there is no mic input. but given the better quality of my outboard set up, I am ahead of the game. The G1000 also feels much better and the extra range [76 keys] suits me. The new sounds on the VA are nicer[Scats ,guitar] but not worth the performance sacrifices. TheE has some nice sounds but not enough variations and choices..The VA style morph is great and simple, but more detail can be done with the G, although more complicated.. Overall I did like the E-600, but rate it last of this group just behind the VA-7..Fran
