I already have a K2500, so maybe that is skewing things, but at the moment, the MoXF (with the Karma software) or the Kronos both have my juices flowing (unfortunately, my bank account isn't as liquid as my salivary glands!), the Kurzweil, not so much...
Add a BK-7m to any of our choices, and you have pretty much the 'do anything' keyboard, though.
I must confess, already having a good Roland product, that the FantomG's kind of underwhelmed me. Pretty good for hiphop, but less impressive on real sounds. Worst organs I ever heard, too! But if you have an arranger by another brand, then maybe good for getting that Roland 'flava'...
I think the ideal is to have one of EACH... I have a Korg, a Kurzweil, a Roland, an Ensoniq, still waiting on getting a Yamaha (but as soon as I can afford one...). That way, you use each one's strengths, and never its' weaknesses. To be honest, three different brand BOTL or MOTL keyboards usually comes out FAR better than just one TOTL WS.
