There are many other options, but I am very happy with my Focusrite Scarlett 2i2, even though it is the second generation. The new one is even better. There are many models, 2i2, 2i4. 2i6 and so on. I used mine to record audio from my old keyboard, that did not have the option to record to USB. After I got my more modern keyboards I record audio on USB and import the file into Audacity. So you really don't need an audio interface just for recording.
