Reply to Pioneer EFX-500 alternative?

Hey folks,

do you know any alternatives to the (freakin' expensive) effects unit from Pioneer?

I thought about making one myself...maybe even out of a simple keyboard.
My problem is the feel of it. Knobs/Faders/Joysticks would be a great addition.

Maybe with a Midifighter ... i really don't know.

What do you believe guys?

Cheers and happy new year by the way
