Bachus, I can see that this controller is for a small niche market. I like its compact form factor in a flight case. However, it's pretty heavy at 52.9 LBS! Once I was thinking of getting the Roland A-88 very compact and 35 LBS. If one is looking for an ultimate 88 key controller, it gotta be the
Pysis K4 Ex As for me, I decided to have a controller at least with a built-in piano sound just in case you don't have your module/notebook. That's the reason I purchased the Numa Stage piano. Now I enjoy the Numa Compact 2x especially its audio over USB feature. So convenient. I wouldn't mind getting a new Casio 88 piano with audio over USB.
Depends on what you expect from the ultimate controller..
Asuming you want a bare controller witouth sound source?
Best piano like action would be the kawai vpc1 bare none..
But if you want all kinds of controll, the physis is definately a great choice, it also has aftertouch.. the only competition i can see is the studiologic sl grand, with mixcraft option if needed..
Where the lmk4 is top knotch is if you want a keyboard that sits directly under another keyboard, giving you kind of an organ feeling with piano keys in. The lower.
The buildset, is unique in that there really isnt much high quallity keybeds for building your own available.. altough, i do think its quite expensive..
