Which discount broker should I go with? Why?

I have around 3000 dollars to invest in Stocks and ETF. I would like a combination between the two. I already have mutual funds with Fidelity but was thinking about doing EFT's and Stocks with another discount broker. What are some idea and personal experience with using other brokers like Scottrade, E-trade, etc. Who is the best for beginning investors in Stocks and EFT. Meaning easlier site, helpful, good customers service, etc.. Also, I am only 22 years old with 9k in mutual funds.

Please explain!

I have been using Scottrade for a little over a year now and have had a great experience. With low commission and absolutely no fees Scottrade has made investing simple and stress free. Their website has a myriad of advanced trading tools that even a beginner investor, like myself, can use. Their customer service is also top notch. Whenever I had a question I just called my local branch and a person would answer every time. Whether your a beginner when it comes to investing or an advanced trader, Scottrade has plenty to offer and I highly recommend opening an account. Though Etrade also has great tools, you will have to pay a lot more for them. Etrade has much higher commission rates and a higher initial minimum deposit. Also, scottrade has so many offices that if you ever want to talk to someone one on one you can just walk in without an appointment or anything. Before I opened my account I also considered Etrade, but after some research Etrade proved to be way more expensive.
