the Scarlett 8i6 has SPDIF in/out.
I am using it since two weeks now and i am more than satisfied with it.
I did a lot of research comparing the different models. Finally i had to choose between the m-audio and the focusrite.
I took the focusrite because it has according to most reviews the better preamps, dsp mixer on board and multiple outputs.
Naturally, this would be my recommendation.
