Generally, I don't like to badmouth a product, but a good friend of mine who has been a Keytron dealer for many years just told me he won't handle them anymore because they break and the mfr doesn't fix. While he was telling me about it, a pro musician guy in the store was looking for a replacement for his Keytron with a busted keyboard. I'd hate to see you buy into a product with lousy support, but George Kaye knows this stuff from 25 years of selling it. He was not angry, just frustrated at having to deal with trades/replacements/repairs. Go with caution, seek alternatives. There's lots of great stuff out there from Yamaha, Korg, Roland.
