Remembering the sub $200 price tag on the Link.USB is really what put things into perspective at the end. For under two bills both your teenage home musician or even professional musician can have an amazing quality 2 in/2 out recording interface. The included Tracktion2 will give you a head start on creating amazing sounding recordings, but being compatible with most recording programs out there won't hold you back from using it with the software you're most comfortable in. Tapco certainly has done a great job of making an excellent interface in a price range lower than most.
