What is the best way to sell shares on the NYSE in Australia?

I am planning some form of investment and trade in U.S. stock market? Does anyone know the best way? What online broker to use the guys and find the most useful and powerful?

I use Firstrade http://www.firstrade.com/. They are cheaper than most big name discount online brokerages like E * Trade, TD Ameritrade, Schwab, and Scottrade. Moreover, although it is more Firstrade cheaper than Scottrade, Firstrade meeting to be better because they offer free dividend reinvestment plans (PRD) that Scottrade does not offer. For more information on opening an international account in Firstrade see the website: http://www.firstrade.com/public/en_us/productsservices/internationalinvestors/.
