I paid £150 for a years worth of Sunday-classes in Mandarin with our local Chinese community centre. Every Sunday for two hours we'd get some great tuition and practice, it's a lot easier to pickup a language when you get a chance to practice it with fluent speakers.
Out of interest, how was your mandarin after a year of that? This thread is now making me feel like a lazy arse for not learning more than a few words and sentences of mandarin, what with having a mandarin speaking wife!
