Hey!
I have the Echo Indigo I/O now which I am very happy with but it seems its time is running out (it refuses to work properly every second time I use it).
So I guess it is time for a new one.
Which one though?
It must not be PCMCIA but it is preferrable due to its size. A small USB card could be good too.
Keep in mind that I bring it on many gigs so it should be durable!
And above all low latency! =)
