Auburn has a 3 year program that I am interested in myself. It’s certainly cheaper than some of the other options and still gets a modest amount of acclaim for its program. From what I understand the first year starts in the summer where you intensively learn sketching and then in fall and spring you take bachelors classes that they feel are the most essential to getting a good foundation in industrial design. Beyond that I don’t know much else about the program. Hope this helped!
