I've been absent from here awhile, so am out of the loop.
A friend of mine just ordered a PC laptop and asked me what audio
interface I recommended for up to $300.
I found the following:

PreSonus Firebox
Edirol FA-66
Focusrite Saffire LE
Echo AudioFire4
M-audio Firewire 410
Mackie Satellite
TC Electronic Konnekt 8
Alesis iO|14
Yamaha GO46

Could you please comment the pros and cons of each, and which
one(s) you recommend and not recommend. Any help is appreciated.

Thanks.
