Strong Engineering still sells screen protectors. They have gotten really expensive though. They are sold in a pack 12 for $27.56. The pic they have up is the original Rocket Ebook. the size is 5.5" x 3.5". IIRC I bought these a few years ago and they fit. Measure to be sure. Still the price may make this a non-option.
