In the old days, trading a penny stock was a difficult task. First, your broker would almost never let you do it... Secondly, quotation services weren't update quotes fast enough for you to make an educated decision. However, in recent years, the onslaught of electronic brokers is making investing in Penny Stocks as simple as investing in large cap exchanges.
We recommend using a major broker if you are just beginning your trading career - the large brokers in many cases will even educate you about the risks that you will possibly be exposed to. E*Trade, Ameritrade, OptionsXpress and others are just a few of the many reputable companies that provide features that are helpful to new traders.
