This is the chain I use in much of my work.

More images...

To show you how this chain is constructed, there is a close-up of one inch of this chain in the first image on the left. And, to give you an idea of what this chain "really" looks like, the image on the left side of this same first picture is (depending on your monitor and display set-up*) "life size". This chain is the second one in the image on the far right.
