I ordered my Fluenz Latin America Spanish 1-5 a few days, and I'm anxiously awaiting its arrival any day now. I studied 3 years of Spanish in high school, as well as a couple on and off years with "The stone" post college. I recently learned of Fluenz, and I feel much more in tune with the methodology it uses. It looks very clean and polished; I love that you get some clarification from an English speaking tutor. My biggest gripe with "The Stone" is that at a certain point you just feel like saying, "Will someone review some xxxx grammar?!"
