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.
