If the Origin is eventually opened up for user maintenance and hacks, I'd be happy too
Beware though, that the Bourns encoder which is used is better than the ALPS offerings. For the big knob, the next level is an optical encoder, but they're not directly compatible mechanically and electronically. The electronics can be easily hacked, but the mechanical bit may be a bit more difficult.
Personally I'd also like to find a replacement for the LCD, with better optical characteristics.
