Unfortunately, Pimsleur is rather expensive. A set of CDs at full price is over $200, and most have three levels to buy.
It's cheaper online: $20 per month, and it'll take you about a month to do the equivalent of a set of tapes/CDs at one per day. (I assume it's the same or equivalent lessons.)
I've learned several languages to the "tourist" level via Pimsleur, but mostly borrowed from the library. Duolingo is a good complement to it for building vocabulary.
