If you're leaning towards Yamaha, the P-125 is definitely a superior choice for its balance of price, performance, and portability. For a more advanced feel, especially in key action and sound depth, you might also want to consider the Yamaha YDP-164 from the Arius line. It offers a more furniture-like model with a GH3 keyboard action that closely mimics the resistance of acoustic piano keys. The sound is rich and it comes with three pedals built into its cabinet for added expression. Both are great options depending on whether you prefer something more portable or stationary.
