Yes they do. Nearly got one from there as well. The good thing about the newest bunch of firewire interfaces is that they are definitely more bang for the buck compared to the older ones like the motus. Like the presonus ADDA convertors are supposedly better than any on the market within that price range. For motu should wait for their new traveller product to hit. But they're always so ridiculously expensive, and there's very mixed reports out there about drivers and support.
So far though because it's a new product the presonus firepod (assuming you're looking at that) has only favourable reviews.
