Very interested in this board as a super portable piano option. 88 full size keys, only 13 pounds, shame no lineouts, but it does have a USB audio interface which is huge and supposedly some ok sounds, "LS Action"? I can order one where I live, but can't test it out, so I'm wondering if anyone has one and can describe what this "LS action" feels like, and how good/not good the pianos are. There's only a handful of reviews online. It looks to be the same idea as the Yamaha Piagerro NP32 which has been out FOREVER, so I'm hoping it has a nicer action and better sounds . . .
