I am seriously about to purcahse a Yamaha synth and have it narrowed down to these two, or perhaps an MO8 if I can' come up with the $$.

I understand the polyphony diffs between the MO8 and the other two, and I think the keyboard on the S90ES is the best of the three.

Anything else I should know about before I decide. Don't really need a sequencer - will use my DAW.

Any help appreciated!!
