se habla espanol?

For the past few years, I have really wanted to learn Spanish again. With a European trip based out of Barcelona very likely in our future, I am even more motivated to learn. I even had great intentions and bought some cheap software off Ebay in the past and ended up selling it at our last garage sale, un-used, un-opened {shows you how disciplined I am}.

Do any of you have any tips for re-learning a language? I have heard Rosetta Stone is the best route, but is insanely expensive. We are talking the equivalent of a college course tuition {which, if it works, I guess is not all that different than taking a course in college}. They do offer a six-month satisfaction guarantee with the purchase. The idea is to get you thinking in Spanish, not just speaking it, which is a concept I like.
