I played the FantomG... it's a great keyboard, but I'm not sold on the ARX cards, yet. Too little choice, not really needed, either (it already has great drums and Rhodes on board), and only two slots. They better come out with a MUCH better one (or two!) soon...

And, it's a good job you have the C1, chas, because I thought ALL the organ patches sucked bigtime!

Hey, before you spring for it, if demos are going to make up your mind, try this one for the MotifXS... http://files.keyfax.com/MP3s/motifator2.0/xs/Demo_Funkalicious.mp3

This is one of the best all round demos for a single keyboard I've heard in a while. Why can't Yamaha put THESE drums in the T3? Check out the realism of the bass articulations, the effects quality, the liveness of it....
