I just received and applied a new screen protector from monoprice.com. The fit and transparency is much better than the product sold by verizon. I cannot tell it's on the phone.
Best part...it costs 76 cents.

You will have to pay shipping but that is cheap too.
Check out their prices on charging cords and covers too. For some reason they only appear to stock these items for the DX.
Monoprice is a great place to buy any sort of electronic cord or (HDMI, component cables, speaker wire, etc.) Very professional company and dirt cheap prices on high quality items. I know this may come across as spam but I'm not affiliated with the company in any way. I'm really not sure how (or why) they sell this stuff so much cheaper than everyone else.
