Frankly talking, after a research of alternatives, I would prefer this one

but also


I got them on Flickr.

They looks alike more capable and rugged.
In case of heavy duty as on Stage, I would really prefer something like that one.

I like their sales pitch:

You manage the Stage in a better way than Jean Michel Jarre itself, due the reliability of the Laser Harp KL-KONTROL!! You will never ever get stuck!

Given the fact that Jarre's unit has a certain reputation these days.
