AFAIK, the XXD series come with a screen protector fitted by the factory - you're not looking at the LCD screen itself when you use the camera - and it's quite cheap/easy to replace. Is this what you're looking for, and do you want an additional protector?
Not quite sure what you mean. How did the LCD screen get scuff marks on it? Were you using the camera without the protective cover - this is fitted during manufacture.
If you have no problems with seeing the display and your only thinking of resale value, then swap out the canon screen cover just at time of sale, otherwise I really can't see the need to speed money on a 3rd party cover.Your LCD screen is NOT scuffed.
