Low-Latency USB Interface?

[WorldIndustries]

Anybody ever use these M-Audio Fasttrack things? It's a recording interface that uses USB. And it supposedly has ASIO low latency. And it's dirt cheap. Sounds too good to be true... Anyone use these before? Have anything good/bad to say about them?

M-Audio stuff tends to be pretty good. any USB 2.0 interface is going to have pretty low latency unless the USB cable is really long. check the s/n ratio, as that may be why it's so cheap. for quality recording, you want a S/N ratio of at least 100db
