"the EM-series look more "toyish" to me than the EXR-5". I agree. The EM10 & EM20 series had a gaudy blue body with gaudy red and yellow buttons.
"the EXR-5 doesn't sound like an EM". The EXR-5 has superior voices to EM10, EM15, and EM25, but marginally better then EM20, EM30, EM50. Never heard an EM2000.
