Optio S - digital screen shade

I have a digital screen shade/bellows type DS1 from www.camerabellows.com which is too big for the Optio S lcd screen. It is made for screens with a diagonal across the screen of 1.5 - 1.8 inches. The Optio S screen is 1.5 inches across the screen.
Anyone got any suggestions where I could get one that will fit and not obscure the controls ? I find taking photos in sunlight almost impossible - improved by holding the shade/bellows in place, but that is not ideal.
