Luis, I suggest that you relax a bit and allow yourself a 2-3 weeks trial period to see if the SD1 suits you or not. The 9000 pro is no doubt an excellent keyboard, more reliable hardware-wise and with a better OS compared with Ketron, but I am afraid that, after playing the SD1, it can be a bit of a disappointment to you.
The SD1 is still my first choice when it comes to playing music, because (IMHO) has the most natural and realistic styles and some of the sounds (saxophones, organs, vibraphones, brass) are also among the best I have ever heard among all the arrangers, not to mention the acoustic piano, which is brighter than Yamaha's (9000) or Roland's (VA7) own pianos.
No keyboard is perfect and for everyone there is a "Yes, but..." or a "Too bad that...", so it all comes down to realize which one has the defects that are most tolerable to us.
