Reviews on EchoAudiofire 4

Hey Ean and everyone,
Question for Ean; any word on when you will get in the Echo Audiofire 4 for a full review?
Question for Everyone else, the last piece of equipment I need now is a sound card and then I will be good to go. I want to make sure I get the best bang for my buck and I will have all I need for at least a few years.
The Audiofire 4 seems to beat out the Firebox and I haven't really read anything that points me in another direction besides these two. So anyone who can give me any advice would be very much appreciated.
I want to spend no more than $300 unless spending a little more gets me a super great card. I would like to have it firewire as that seems to be the way to go.
Thanks so much guys
