Which is better for a beginner taking lessons?

The Yamaha P-143B. Its graded-hammer action and CFIIIS piano sound build better habits, and the 10 voices keep things simple. The Donner is cheaper and has lesson mode, but its piano tone and key consistency draw more complaints.

Is the Yamaha worth about $190 more?

Yes if you mainly play piano. You pay for the Yamaha action, grand piano sample and USB audio interface. If you want many sounds, rhythms and a screen on a budget, the Donner gives more per dollar.

Which has better polyphony?

The Donner, at 128 notes versus 64 on the Yamaha. That matters for layered sounds and sustained pedaling. For solo piano practice, 64 notes is usually enough.

Which is easier to move?

The Yamaha. It weighs 24 lb 8 oz (11.1 kg) against 15.4 kg (about 34 lb) for the Donner, and it is narrower and shallower.

Can I record with either one?

Both record internally and connect over USB-MIDI. The Yamaha adds a built-in USB audio interface, so you can send audio straight to a computer at 44.1 kHz, 16-bit stereo.

The Yamaha has the stronger track record. Donner buyers report some keys failing within a month and power adapters breaking after a few months, while Yamaha's GHC keyboard is a proven design.
