Where to get keyboard/controller mech. parts?

[Ben Stuyts]

Hello,

My first post here. Very interesting list!

I need some additional modulation controls for my setup, and I thought it  
might be fun to make something like that myself. Might even add a simple  
keyboard, so that it becomes sort of a master keyboard.

I was wondering if there is a place (preferable in the Netherlands or close)  
where one can get modulation wheels, ribbon controls, and other mechanical  
keyboard parts. I did a search on the web, but couldn't find anything. Only  
complete master keyboards, etc.

Thanks,
Ben
