SP-320 : Would recommend as a portable gig piano or a hobby instrument

Feather light in comparison to the rest of it's 88-key siblings. This is no exaggeration that you can simply walk in the room with a full-size piano under your arm.

Sound sampling is amazing, rich timbre from both pianos.

Features wise the control panel could benefit from printed hints for touch, layering volume, transpositions and other features that are not possible to remember off by heart.

Touch wise the piano is what you expect from a light weighted keyboard, you will have to get used to the response. If you only ever played the pianos with hammer action keys, you might find it unusual.

Must remark on a perfect match with the wooden stand, once put together it is very pleasing to the eye.
