The one I was looking for is the hard plastic with the black border that goes over the lcd on the gp2x.
Okay, the person I bought my gp2x from has a few dozen of the hard and film plastic ones. If you want one inquire at email address:
ebay[at]thebige[dot]tv
SPAM filter: convert [at] to @ and [dot] to .
Note: I am not affiliated with this person, I ordered the gp2x and accessories from there and it came pre-tested and works perfectly. I just ordered a few of the hard plastic screens and plastic films from there also.
