I would recommend looking for the audio CDs by Michel Thomas. I have used his system to learn French, German, a bit of Italian, and now working on Spanish. His system gives you a very quick, basic introduction
to the language. If you want to speak a language well you will have to go beyond his introduction
. But as a starting point, I have found his CDs to be excellent.
What's more, I have found his CDs at my local library, so up to this point I have not had to actually buy any of them. I borrow them from the library, rip them to my hard drive, copy them from there onto cassette (because my car does not have a CD player), and then listen to them as I drive back and forth to work. After going through each tape 3-4 times I find myself quite prepared to move onto more advanced lessons on the language.
