we recorded an entire CD with a UX8, did exactly what it promised to do.
The firepod may be better (I will have to take your word for that) and firewire has better throughput (unless you are running USB 3 which the UX8 isnt) but saying that line 6 products never do what they promise is not true.
Are firepods really that cheap used? I just have the pod studio UX2 now and may upgrade at some point.
