Donny, if I may suggest something: get a Yamaha Montage or MODX. Why? Because the built in arpeggios offer a lot more possibilities than styles on an arranger keyboard. Better yet, add an arranger to the setup. You'll have the best of both worlds; the arranger for its styles, and the synth for incredible right hand sounds, in-depth sound sculpting, and of course, its Arpeggios.

I have a Motif XF, and I really enjoy its 7,881 arpeggios. The Montage and MODX have even more!

There's nothing like a synth as far as its features and sounds go. Or, get the Genos.

I wish you the best no matter what you choose.

My two cents.

P.S. May I ask why you decided against the E-A7? Just curious.
