The Lexicon I Onix U42S is a audio interface that you can get online used for around 300 dollars like I did about 6 months after it first came out. The I-Onix has 4 input and 2 output USB 2.0 with a 44.1kHz to 96kHZ sample rates. The unit has a very unique and futuristic type of design. I have not really seen many interfaces that have this type of look to them and can still hold up on everything they say it can do.
