They are both about the same price. The casio comes with a stand. Does that meanthe synth is less good? Which one sounds better and has better features. I want to be able to create lady gaga sounds and might be starting a band. I don't care that the casio has more keys. I just want the better sounding one that the sounds can be manipulated easier. Also, the cEil has a better midi and an sd slot. What one is better? Also, are there anybetter digital synths out there. Or a keyboard with good synth features? ThAnks. Also, I kinda prefer them without built in speakers but that doesn't really matter unless the synths are equally good. Thanks. ( ilike the look of the mm6 but it has terrible midi and no sd slot. Anything similar but with those features and no speakers around 600 dollars new)
