Feature:
The weighted keyboard is excellent -- not quite equal to Yamaha's, but as good as Roland's or Kurzweil's. The SP-200 includes a sustain footswitch, but the half-damper pedal to replace it is an optional $60 add-on. The power socket is one of those small round ones that uses a regular "wall wart" AC adapter, and so is more fragile than a proper three-prong plug. Fine for a house, but not that great if it were being regularly plugged and unplugged on stages. Similarly, it's odd that both the power button and headphone jack are on the back of the housing, since that's not convenient for anyone. The LEDs that indicate the SP-200's current settings are adequate, but it's sometimes hard to know exactly what those settings are at a glance

Feature:
It did not include accessories, the lack of ability to split the keyboard is curious. The midi implementation is from the dinosaur era

Quality:
I can be a bit roough on my gear, one output channel has gone out and since I Have to run stereo or go crazy that is a drag. Generally, though, the product was well designed to take typical wear and tear and has a clean, simplicity of design

Value:
No

Sound:
THe separation in the layering of the samples is too abrupt. A good electronic piano should have at least 5 layers of dynamic sampling. This seems to have just two, there does not seem to have a good mezzo-forte or mezzo-piano. In addition, not enough samples are taken of the full range. The upper midrange is often tinny while the bass is booming. To compensate, I run the piano through a stereo Crown amp and have one side go to a Peavey 12 cabinet (which is a bit mid-rangy) add run the other side through a Yamaha 12 in cabinet (both have horns and passive cross-overs). The result is fairly good. If you are using an electric piano and not using a good stereo rig you are being quite foolish and getting about 10 cents on the dollar for what you paid for the piano. Put your money on your sound reinforcement first!

Support:
I have not

Overall:
I will buy a new piano as soon as I am reasonably sure that there are more than 3 sample levels (The Yamaha 250, which seems to be the best, still only has 3). I figure I will use the Korg for 2 or 3 more years

Feature:
The half-pedaling option sounds appealing, but who cares if it doesn't sound like a piano to begin with. Inclusion of a metronome is nice.

Value:
It wouldn't be a bad practice instrument in a classroom setting -- if the keyboard is very good. I have only listened to the demos and read the manual.

Sound:
If you're looking for something that actually sounds like a piano, make sure you listen to the MP3s on this site. The piano sounds as if they're looping a very short sample for the sustain and sticking on a separate attack. The overall impression is almost totally fake. Entirely unacceptable for solo work. Note that while they advertise 60-note polyphony, the primary piano sound takes 2 oscillators per note.

Overall:
I've been looking for something to replace my old Kurzweil Micropiano module and battered Fatar keyboard. This isn't it.
