Depending upon what you consider to be
"cheap," Edirol FA-101 is
(firewire)
is ironically cheaper (approx. ~$300) than UA-101 (usb, ~$450), although
from what I read the UA has a much more elaborate routing capabilities.
That
being said, we have over dozen FA-101s in DISIS and they work perfectly
with
Linux (ffado), offer 10 i/o, 2 very good preamps, and MIDI. If you have a
MBP you can run them without external power (they run off of the FW
cable).
Forgot to mention, if I really had to nitpick regarding these, it would be
that the line outs are +4dB.
