I see you are looking at the Echo Indigo. I have one. I use it with my
laptop and about 100 pounds of mics, mixer and cables to record a band I
play in. Be aware, unless Echo has solved their problem, that boot up
with a Windows XP machine is a bit of a crap shoot. I sometimes have to
try three or four times before I can get it all to play. I am not a
computer guy, but I am not the problem. The symptoms are that the laptop
freezes during boot and you just have to start over an over until it
works. You have to keep the the Echo unplugged, start the laptop, plug
in the Echo "at some point" during the boot so the laptop will recognize
the Echo, but past the point where the Echo causes the laptop to freeze.
I was never able to determine just what "that point" was. It is a mess.
When I called Echo they acknowledged the situation, but defined it as a
problem with the Windows O/S. Right! The flea complains that the
Elephant won't let it on for the ride....
