Personally, Donny, I think the MOX6 is a terrific little instrument, but used as an arranger, the PSR-S910 blows it away feature for feature, and only weighs approx. 5 lbs more, and that's including on-board speakers.

If you are using primarily SMF, then perhaps the MOX6 might be better, but it still can't compete with the current MOTL arrangers, in my opinion.
