Any recommedations for good sulfate free shampoos, would be much appreciated?

There is a company in Australia that is in the process of developing a range of hair products for men, that are free of sulphates and other harsh chemicals. They are not registered yet and are not in production yet but it shouldnt be too long. The guy developing it is a friend of mine and if you want I could see if he has anything ready to send to you. I am acutally being his guinee pig at the moment and so far the products are great.
