Can the Yamaha CK88 really run on batteries?

Yes — the CK88 can run on 8 AA batteries, making it uniquely self-contained for an 88-key stage piano. Battery life is approximately 5 hours at moderate volume. This is genuinely useful for church gigs, outdoor events, and rehearsal rooms without convenient power. No other 88-key stage piano in this class offers battery operation.

How heavy is the Roland RD-2000, and is it manageable for solo gigging?

The RD-2000 weighs 21.7 kg (47.9 lbs), making it a genuine two-person job in a flight case. For solo gigging, this is a real consideration — you'll need a dolly or roadie assistance for regular transport. The Yamaha CK88 weighs 13.1 kg (28.9 lbs), which is manageable solo. The RD-2000's weight is the direct cost of its PHA-50 wooden key action.

Does the Roland RD-2000 have built-in speakers?

No. The RD-2000 is designed exclusively as a professional stage instrument assuming you'll always be plugged into a PA or amplifier. The Yamaha CK88 includes built-in speakers (capable of 15W output), making it usable as a standalone practice instrument and for small rehearsal rooms where a PA isn't available.

Which is better for a church keyboard player?

The Yamaha CK88 is typically the better fit for church musicians. Its built-in speaker means it can double as a standalone instrument for small services. The dedicated organ section with real-time drawbar control makes it ideal for worship settings. Its battery power and lighter weight make setup and teardown faster for volunteer musicians.

Is the Roland RD-2000 worth the extra $1,100 over the CK88?

If you need the best possible key action and master controller functionality, yes. The PHA-50 action on the RD-2000 is genuinely in a different class from the CK88's GHS action — it has real wood keys and feels closer to a concert grand. If your priority is versatility, portability, and built-in sounds for live use, the CK88 is the more practical instrument.
