JD - if you happen to browse the zillions of posts in here about this topic, you'll definitely and frequently come across the mention of Focusrite products. I want to put in a good word for them.
1. Good options. Low latency.
2. Excellent, clean pre-amps.
3. Offerings to fit low budget as well as expanded budget
4. Good software interface that accompanies the hardware. That means, easy to use (compared to others).
5. Good reputation - drivers work, plug and play, typically people find the products great and don't complain
Bonus round:
6. Focusrite has a thing called the Focusrite VRM Box (you don't need a Focusrite audio interface to use it, but you do need SPDIF outputs - which Focusrite audio interfaces often have except for the lowest end ones). The Focusrite VRM Box is a low cost item and can really help with mixing if you use headphones for at all or some of your mixing.
