Personally I would recommend you build your own. What I would do is find a word in Chinese (any word, but preferably not some obscure one like paediatrician) and then enter that. Then find some online dictionary like yahoo.tw and just copy and paste some example sentences and translations. Start simple, don't try to push yourself or you will jsut end up getting frustrated. Take baby steps.

For Anki, I recommend also going to download plug-ins and download the pinyin one (if you sort plug-ins by download count then it's the second from the top, under the Japanese one). With this, when you enter a Chinese sentence it will automatically give you a translation or definition and also produce the pinyin complete with tones.

The way I tend to create my cards is by having the front of the card in Chinese and then pinyin and English translation on the back, as this also helps with reading comprehension and character recognition.

If you want, I can send you my basic deck (only about 550 cards at the moment).

I would also highly, highly recommend reading ajatt.com. This is by a guy who learned Japanese using an SRS program (and now also Cantonese). If you have a flick through some of the earlier articles and his methods, I think you'll find it really useful and motivating.
