What ever happen to the NEKO, they are still making it. Never mind some will be daft enough to buy, but no a SZ member, hey!!!
At $6,369 .... not me for sure. I think the Korg Kronos provides a more cohesive environment at a lower price than either of these products. Like Diki points out rolling your own is a massive task. I'd much prefer to buy a keyboard that already has a good working music engine. I want a keyboard to be ready to perform with straight out of the box.
