Cherry Picking The Diamonds From The Stock Market

How do I go and buy penny stocks?

My regular stock brokerage firm does not deal with penny stock. How do I find a legitmate penny stock trader?

Don't do it. You don't know what you are getting into. Save some money and invest in DRIP. There are many companies allow you to buy stocks directly. Any stock broker will allow you to buy penny stock because they want to make money. Don't waste your hard earned money. Better off doing something else.
