I used to work at Banc of America Investment Services before I quit to go back to school. I can safely say that I would never do business there. Unless they have cleaned up their act in the ten months I haven't worked there, the place must still be a mess.

I use http://www.thinkorswim.com for mutual funds since you get 3 free mutual fund trades a month.

I use http://www.zecco.com for my standard stock trades as you get 10 free a month. Definitely not the most fully-featured broker, but it works and it's hard to argue with no-commission trades.

Go with the cheapest - Interactive Brokers

Damn I hate their security device though. It's kind of irritating to have to enter the security codes every time i want to make a trade. And if you're a frequent trader, it'll get on your nerve (on the flip side, it prevents over-trading)
