I'm going to ugrade my hardware froma us-122 to a multichannel either PCI or firewire interface. I've been leaning toward the echo layla 3g because of it has all the connections and echo's soundcards are good. I noticed though that it provides near zero latency monitoring while my us-122 provides zero latency monitoring. I'm thinking about going with the firepod now, but it would cost more and I would need to install firewire port in my comuter. If I wont be able to notice the difference in the near zero latency compared to zero latency issue, I'll go with the Echo Layla.
