I got this one:

To be honest, I am not very happy with it.
It tends to not stay completely folded out, does not sit tight on the screen and makes it very impracticable to use the touch screen, even though it has this flexible bottom. And it helps less in sunlight than you might think.
All in all I tend not to use it anymore but just shade with my body/hands or use my Shogun Inferno in direct sunlight. Alternative could be the BMD viewfinder or one of the ultrabright SmallHD monitors.
