The Steinberg does look nice.
At work, we've finally got the Focusrite Pro 40 - so far seems pretty good.
its on a Mac Pro, going into the FW800 port on the back, and if you connect a hard drive to another FW port (as we have to quite a lot), the Focusrite momentarily loses its connection and the speakers 'pop'.
I know we haven't got an ideal set up, but just a word of warning!
(we're going to get a pci fw bus)
