This one is for Melanie if you have time.

The Melanie's suggestion is widely used. Cheap, simple, easy... wanna have another language... few cents later it's done.... same thing when the lettering disapear (not often) or damaged (often).

I already thought about membrane myself too... most of the time, they just don't worth their price. Guess why it's so expensive?

Few cents tact switch, few cents plastic and not much. O.K there's few more assembly steps so far... it's the ONLY down side.. at least to me.
