Rikki,
Yep some of the same interest in types of music...you converted some Andrew L Webber styles for me. From a critical listening view....if you get some time...tell me how the Orchestral sounds quality is, please. You know the sounds for playing beautiful instrumentals. ( I don't sing so sound quality IS my voice).
Good to hear about the 50/60 styles being nice. Yes, due to cost I am leaning towards the SX900 now too. I hope the keybed is a lot better than the S970 as it was noisey and toy like to me anyways.
Later....
Lee
