I agree with Donny. Nobody will be able to free you from your anguish, only YOU can make your choice. You will easily test the SD1 at the portuguese distributor in S. Joćo da Madeira. The Yamaha will be more difficult to test: there's no distributor for Portugal, only a distributor for Spain/Portugal located near Madrid (Yamaha-Hazen Musica). The shops that carry Yamaha brand rarely have the 9KPro. If you want I can send you the list of all the official sellers of Yamaha keyboards in Portugal. As for the Madrid distributor, I can provide you a good (e-mail) contact at Hazen: I met this guy at Musicalia show, in Lisbon, last week (a kind of portuguese NAMM); he will surely help with your questions.

I should add that, despite the less reliability (which I might agree with) of Ketron, the portuguese distributor has provided me a quick and good support. Absolutely no complaints about it.
