Question for you B3wannebe. Do the Nord boards come in only red?
Why would you want any other color? A board that sweet has to stand out physically and visually! LOL
Really though, I'm not trying to convince you to get the Electro, but your question was about a keyboard with the best ORGAN sound, which the Electro is. If you want more sounds or drawbars, however, then you might want to get the 2600 or that other one that I think Roland makes. VK Combo? I don't remember the name. I just saw it yesterday too. If you want sequencing then get the Motif or Triton. The Electro is just a stage piano with organ.
....BUT....The cheapest option, if you already have a keyboard, is to get a Roland VK-8M. You'll get the ability to play two manuals in a smaller and lighter package. It all depends on what you want. I'm starting to go more with modules and controllers though. You can get the same sounds, upgrade easier, and it's cheaper.
I'm actually looking at getting the Electro module, because I already have 2 keyboards and an organ.
