Bluebird,
I agree with DonM. You are over-thinking the voice ROM.
Yamaha PSR550, 8 megs wave rom with 700+ voices.
Roland EM20, 8 megs ROM with 325 voices.
EXR-5, 8 megs voice ROM with 510 voices.
The PSR550 has unbeatable sweet & cool voices, but other voices not that impressive. Roland EM20 has many very good voices and EXR-5 has more voices and yet has slightly better voices in some categories. They all have 8 megs voice ROM.
