I got the BoxWave brand screen protector for my 770. It's fairly rigid and fairly easy to apply. If you mess up, like getting dust under the protector, you can just rinse it off and try again. It cost $13 for one sheet. In comparison, I bought a screen protector pack for my digital camera. I had to trim it to fit. It was foggy and impossible to get the bubbles out. Price was $10 for 6 sheets. The BoxWave, while more expensive, is a much better product.
