*ist DS LCD screen same size as...?

I want to get a screen protector (soft thin film type) for my *ist DS. There aren't many described as suitable for this model - so I'm wondering if any other cameras have exactly the same size and shape screen, so one intentended for that would also fit my camera.

[Same question for Optio s5i posted in the Optio section]

I've found some available for the DS from a German ebay seller - but feedback from buyers raise doubts about the quality. I know screen protectors can be very good and clear indeed after getting one for my mobile phone.

Cheers,
