US product design programs VS. programs abroad

I already have a bachelors in an unrelated subject and would like to go to design school. I’m particularily interested in product design, so am looking for undergraduate programs.

I know people say that Art Center is the best with great work facilities, faculty, and connections to companies. Since it is expensive, I wonder if there are any other great programs out there in the world that are more affordable.

I saw the list of the best european schools. How do these programs compare with the programs in the states?

It would be a great life experience to study abroad–are there disadvantages to think about?

Would appreciate your input, thanks!

1st question: undergrad or grad?

2nd question: what type of design do you want to do? What connections do you want to make with what you have already done? (if any).
