Thanks for the response. I just found out that the Audiofire series supports GSIF 2.0 so that's good. I also saw that Echo is releasing 2 new firewire interfaces - the Audiofire 2 and Audiofire 4. I might go with one of those as I don't really need that many inputs/outputs. The only question is when exactly will they be released and how much will they be? Echo lists them on their site, but they aren't available at any internet store.
