Have you checked E-bay.com?
When I was looking at getting a 10D I found a company selling protector that were made out of a very durable plastic. The features were:
1. This was made to fit just the 10D and was not universal like the PDA and Camera protector screens.
2. When you purchase one of these remarkable protectors you will also get a kit that will help you to pre-clean the screen so to get a clean surface that will provide a better hold.
3. The protector actually serves a dual purpose where it protects your screen and also allows you to attach a hood over the screen and also screen multiplyers for better viewing.
4. The plastic is made out of very durable material that will not crack, fade, color, or scratch under normal conditions. It will not fall off either due to the strong bonding glue that is used to place it on the screen.
To the comment made about the 10D already having a protective screen. This is true to some extent. The protection is not all that great, it is similar to scratch resistant lenses in glasses. I work in the Digital Imaging department at my local Best Buy and I will tell you that they can be scratch and an extra protector can't hurt. I hope that this has helped you and I will try to find an auction number of one of these items to give to you, so you can check it out for yourself.
