Hi there,
Ask these guys for advice on the LCD before you commit to buy, they are the hardware and repair branch to Access-Music:

They will likely also stock the relevant parts if needed, but check beforehand.
I happened to buy some pots (potentiometers) for my Indigo 1 from those guys and soldered them in myself.

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
