You might try Pimsleur (& others) at your free public library
(Atlanta, Georgia, USA)
After reading some reviews of Pimsleur, I must suggest, that if you feel that the asking price is too high for your budget, look for a copy at your local, free public library. It is amazing how much audio material (as well as printed) is purchased with tax dollars, and left to sit on the shelves of public libraries, with barely any signs of use. Some copies have no sign of wear!
In my humble opinion, Pimsleur is superior to the others. I really cannot add anything to what has already been said. I purchased Pimsleur comprehensive, after sampling all of the available foreign language learning methods, at the free public library. I quickly tried each one, at the library. The public library made it easy, saving me the extra trouble of first purchasing, and then mailing or carrying back the ineffective methods, for a refund. About the only method that my local library does not have is Rosetta Stone. But Rosetta Stone offers a trial, with a money back guarantee.
(In my humble opinion, Rosetta Stone is overpriced and ineffective. I would not use it if were provided at no cost, as it wastes the student's time. But that is another review.)
