The S-03 is a basic budget synth that sells for $499.00 It's not bad sounding. Contruction is good, pitch and mod wheels are large and good quality, screen is so so, keyboard action and quality is another story. Personally I didn't care for it. Even though it doesn't have a sequencer, or styles it ships with XGLite software for computer recording. In some places it advertised as a "budget synth for midi recording". Basically to get newbies started.
