I've narrowed it down between these 3 companies to rollover a inherited ira in, but I'm contemplating which service to use? I intend to learn options and bonds, and very little mutual funds which seems like Ameritrade would be wise to go with. On the otherhand, it seems like fidelity is a good choice, and I'm hearing people say Vanguard is cheap (looks like for mutual funds).

Which one would you guys pick, given the situation?
