I've been using the Tascam US-122 for several months now, most recently to get some field recordings of environmental sounds with my laptop. Works perfectly even at 96k/24bit while providing phantom power to my twin AT 4050's. Also use it for working with Reason and it gives me about 2ms of latency - quite good. Some people are prejudice against anything that is still working off the USB 1.0 standard like the US-122 but so far on everything I've used it on and tried it with, it performs A+. Nice solid-feeling unit too.
