I have 4 brokers... Suretrader, TD, Etrade, Fidelity... I would go with etrade if you are looking for just one and want to trade all pennies. TD is my favorite due to the think or swim platform, and better execution speeds, but DTC chill stocks a no-go. Fidelity is piss-poor with execution so i would avoid that one, i'm going to be closing my account there.
