I still have my SP4-8 and Love it! Brushed Aluminium case.. TDP classic piano, good e.pianos as well, KB3 tone generator, VA1 analogue tone emulator, and a good sort of PC3 orquestration samples. Plus good keybed FATAR (Nord2). Don't really thing the SP1 is better, despite both, were/is (on each case for the release moment) the Pro entry level of Kurzweil stage pianos line. I just don't think can even compare them. * polyphony don't really rob my sleeping.
