Been using the ClearTouch Anti-Glare since day one on my Mogul. Had used them on all my Treos as well and really think they are the best for viewing in the sunlight. The Crystal ones are good and don't even look like you have a protector on it, but they don't work as well outdoors and they attract fingerprints like crazy. The anti-glare don't hold fingerprints or dust as much. $12 is kind of pricey, but I've gotten over a year out of them so that's only about $1/month.
