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