I recently started studying Russian (about 3 months). I've been using the Pimsleur Speak and Read Russian during my commute to and from work, and I think it is a great program. The only bad thing is the price, but fortunately I was able to get it from my local library, so I didn't have to pay for it.
Has anyone else used the pimsleur audio courses? How did you like them?

I have also been studying the penguin Russian course and have found that book to be very good.
So far the combination of the audio (pimsleur) and the text (penguin) have been working out pretty good for me. I have been able to stay motivated longer than previous attempts to a foreign language. But I guess only time will tell if I can actually learn the language.

How long does it typically take to learn Russian?
