I had a free trail with this site:
Learn Chinese|Learn Chinese Online|Learn Mandarin|Learn Pinyin|Chinese Learning - ChineseTime last week. Though the sound quality was a bit choppy at the beginning (it¡¯s ok after I turned off my webcam) , the whole lesson went very well. Instead of a sexy young chic, the teacher was a very nice, professional mid-aged lady. I think this is the place if you are seriously about leaning Chinese.
