I don't think that Casio directly competes with the other brands that are more often discussed here.
I think they have produced certain models (like the WK-3500) that sound great, with very good functionality (midi, L/R outputs, media card storage, etc).
Because of the useful components and the good sound (produced from 32-note polyphony yet!) people tend to start A/B comparing with more expensive models with 128-note polyphony (plus other miscellaneous goodies) and respect for what Casio has accomplished, and at such a great price, goes right out the window,
Not Fair, I say!
I have a lot of respect for Casio and what they have been able to produce for the money.
Claudiu, that tape is silver duct tape which you can get at any hardware, kmart, etc.
But the lettering in the names CASIO and CLAUDIU are pretty close.
If I were you, I'd take the keyboard to the local auto/body shop and have them do some light sanding and get your own name etched into it. The Claudiu 3500
