I have a close Chinese friend who listened to some of the recordings on my IPod - she said go with CLO. She constantly remarks on my great accent which she says is always the biggest problem.
I travel a great deal and knowing Chinese, even a little, can only be helpful when 1/4 to 1/3 of the worlds' population speaks Mandarin Chinese. You are doing a great job - I seem to be going very slowly; however, my friend says I am not but rather she is impressed with where I am and again is most concerned about the correct accent.

Your website and podcast have been extremely helpful to me in my recent trips to China. I've become a premium subscriber because it's been so useful. I've tried several other Chinese language resources,but have found yours to be the best.

I am a performer and I decided that since I would be spending so much time in China, it would be nice to learn some of the language. I thought it would be respectful to at least try, and based on my experience, the Chinese people love it when Americans try and speak their language.
