Although the hardware is what's being advertised, the Legacy Collection that comes with it seems to be the better deal (keyboard is just a bonus
)
I have the M1 which is really nice and I think I got it for $50.....
"
Korg made the mircoKEY61 even more irresistible than ever by bundling it with their Legacy Collection soft synth bundle. That means, when you add a Korg microKEY61 to your music-creation rig, you also get a complete set of five awesome virtual vintage synthesizers. This collection includes the MS-20 analog monophonic synthesizer, the Polysix polyphonic synthesizer, the versatile Mono/Poly analog synthesizer, the M1 (Korg's original music workstation), and the Wavestation digital synthesizer. Altogether, these incredible plug-in instruments add extra value to this already amazing keyboard controller."
