Eighty-eight keys, and what they weigh · review
A slim 88-key board with Casio’s Scaled Hammer Action II and, unusually at this price, the SP-3 pedal, music rest and power adapter already in the box. Ten sounds rather than hundreds — the money went into the keys.
The bottom line The pragmatic first piano: weighted keys, the pedal in the box, and a depth that lets it live on a desk rather than in the way.
Casio’s CDP line exists to answer one question — how little space and money does a properly weighted 88-key piano need? The CDP-S110 is 99 mm deep and 10.5 kg, which is closer to a controller than to a console piano, and it still carries Scaled Hammer Action II across the full keyboard.
The ten sounds are the trade. An arranger at this price will list hundreds; Casio lists ten and puts the budget into the action and the cabinet. If you want accompaniment styles and a screen, this is the wrong instrument. If you want to practise scales on keys that push back, it is a very direct answer.
What makes it unusually complete is the box: the SP-3 sustain pedal, the music rest and the power adapter are all supplied. Three things that are commonly sold separately, and each of which turns a working keyboard into a frustrating one when it is missing.
Casio also lists a six-AA battery option. That is rare on a hammer-action instrument and worth knowing about if the piano has to move between rooms.

It is a footswitch supplied by Casio for this instrument, so polarity is correct out of the box — the failure that makes a keyboard appear to sustain permanently does not arise here.
Casio lists six AA batteries as an alternative supply. They are not included, and the listing does not state a runtime.

88 keys · SuperNATURAL · headphone output
Roland’s entry into the FP series: 88 keys with an ivory-feel surface, the SuperNATURAL engine, and a keyboard mechanism Roland describes as quiet in itself — the detail that decides whether a flat-dweller can practise at night.

≈ $500 / £390 / 400 €
88 GHS keys · three pedals · console cabinet
A console piano rather than a portable one: 88 Graded Hammer Standard keys, three pedals and a cabinet that stays where you put it. Yamaha also fits a volume limiter, which sets a ceiling on output.
