If you started this thread a few months back, I would have also said AZH, but it has doubled in price in the last few months. Even after its big rise over the last year, it could easily increase by five times over the next three-four years.
As someone else mentioned, you want to look at M/C rather than share price, unless you are trading, in which case the 10-12 cent mark is danger time.
