Buying keyboards pianos can mean two very different things: choosing an instrument to play or selecting an accessory for one you already own. In this group, the Roland GO:PIANO88 PX and Kawasaki Audio Pro 37 are playable keyboards, while the M-Audio SP-2 is a sustain pedal and the Yamaha SC-DE61 is a backpack-style soft case. Start by deciding whether you need a keyboard's key range, more expressive pedal control, or a way to carry a CK61.
Quick take
For an instrument with a full 88-key layout, the Roland GO:PIANO88 PX 88-key Music Creation Keyboard is the direct match. The Kawasaki Audio Pro 37 Electronic Keyboard takes a more compact 37-key, beginner-level approach with battery-powered operation, built-in effects, a speaker, and recording/playback described in its title.
The accessories serve focused roles. Choose the M-Audio SP-2 Universal Sustain Pedal when an electronic keyboard needs a universal-compatible sustain/damper pedal with an anti-skid feature. Choose the Yamaha SC-DE61 Backpack Style Soft Case when the goal is carrying a Yamaha CK61 keyboard in a soft case.

Product notes
Kawasaki Audio Pro 37 Electronic Keyboard
The Kawasaki Audio Pro 37 makes sense for a player seeking a smaller beginner-level electronic keyboard rather than an 88-key format. Its 37-key synth-action layout, battery-powered option, built-in effects, speaker, and record-and-play focus give it a self-contained set of music-making features. The multicolor design also sets it apart visually from the black Roland keyboard and accessories. A meaningful limitation is its compact 37-key arrangement, which leaves less key range than the Roland GO:PIANO88 PX. The instrument is described as new and still mounted to cardboard, although its box has wear and stains from storage and moving.
M-Audio SP-2 Universal Sustain Pedal
Pick the M-Audio SP-2 when the keyboard is already in place and the priority is adding a sustain/damper control. The black pedal is described as universally compatible for electronic keyboards and includes an anti-skid feature, making it the focused accessory choice at the lowest listed price in the comparison. It is not a keyboard or music-creation instrument; it is intended to complement one. Condition is the trade-off here: the pedal is used, and the description notes slight pitting on the foot pedal. That makes it a targeted choice for pedal functionality rather than a replacement for an instrument.
Yamaha SC-DE61 Backpack Style Soft Case
The Yamaha SC-DE61 is the choice centered on transporting a Yamaha CK61, with its title identifying a backpack-style soft case and its compatibility listed for Yamaha electronic keyboards. Its black finish and Japan origin fit a straightforward carrying-accessory role. The price places it much closer to the cost of a playable keyboard than to the M-Audio pedal, so it is most suitable when a CK61 case is the actual need. It is also a soft case rather than a keyboard, pedal, or recording tool. Shoppers seeking keys, sounds, or sustain control should look instead to the Roland, Kawasaki, or M-Audio entry.
Roland GO:PIANO88 PX 88-key Music Creation Keyboard
The Roland GO:PIANO88 PX is the clearest fit for someone who wants an 88-key music creation keyboard and the full-sized piano-style layout described for learning and more complex pieces. Its description also characterizes it as lightweight and portable when using battery power, combining a broader key range with a portable use case. The black GO-88PX is the highest-priced item in this comparison, so it asks for the largest listed outlay. It is the stronger directional choice when the central requirement is 88 keys; for a compact beginner keyboard, the 37-key Kawasaki takes a distinctly different approach.
Final recommendation by use case
Choose the Roland GO:PIANO88 PX if full 88-key play is the deciding requirement. Choose the Kawasaki Audio Pro 37 for a compact, beginner-level keyboard with recording/playback language in its title and built-in speaker and effects. Add the M-Audio SP-2 when sustain control is the need, and select the Yamaha SC-DE61 specifically for a backpack-style CK61 soft case. The right pick depends less on a single price comparison than on whether you need an instrument, a pedal, or a carrying case.
