OK - I know this has been discussed many times but -
I just got my new 7D and thought I'd check with the Canon Service Center on a replacement cover for the main LCD screen - just in case.
Guess what - they don't make one for the 7D - its the whole LCD that gets replaced - and it costs $118.39 currently. They did say that they do make a replacement "cover" for the top LCD screen - $7.15, but on the 7D rear screen you pull out the entire LCD, unplug it, and put the new one in.
They did agree that on some other bodies (like the 40D) there is a "cover" over the LCD and they run around $13.00.
This makes me rethink that $30.00 Giottos glass protector a little more.
If anyone knows something different, or has had to replace the 7D screen, please let me know. But this is what the Parts Department at the New Jersey service center told me - specific to the 7D - they even indicated there was a "note" in the parts listing about not having a cover over the screen.
