US-800 is again at $99 at Musician's Friend.
http://www.musiciansfriend.com/computer-...-midi-interfaceI've had a couple go arounds with both audio and midi tracking/mixing with this device.
Pros:
1. The mic preamps seem pretty danged clean. Much cleaner than I expected for $99. I would say they are better than on my PreSonus FireBox. Unfortunately I can't do a shoot-out between the devices. Don't expect loads of gain with dynamic mics. I have an ElectroVoice PL80a (designed for stage use, unidirectional, etc.) and have to crank the pre-amp input knob to 100% for close-mic'ing a classical guitar. I know, not an ideal mic for the situation, but I 'run what I brung'. Still a nice clean signal but I would have liked perhaps another 5-10 dB of gain.
2. While connected to the computer, the device can function like a mixer, don't need your DAW software open to set mic levels.
3. It is 6 mic or line inputs, with phantom power, for $99 - almost unheard of.
Cons:
1. You MUST wait until your PC is completely booted, before powering up the unit - otherwise Win 7 will not see the device.
2. You MUST reset the latency on the unit's GUI each and every time you use it - hassle.
3. I was at the middle of a 3 hour recording marathon (that's a marathon for me, don't have the kind of time I used to for this stuff) and Win 7 decides that it no longer recognizes the device - right in the middle of a tracking session. Crackles, then just plain stoppage of the DAW software. Had to exit all the way out of DAW software then reboot Win7, turn on the unit, reset latency to my desired setting, etc.
4. TASCAM customer support takes over a day to reply to inquiries. The unoffical but only existing tascam message board/forum is a pay-for service - can you believe that? It's a small fee, but still, you would think Tascam could host something like this without charging customers. They choose not to host any user-contributed help and allow an outside entity to do this.
