When a commish-free ETF is available from more than one broker, ETFDB doesn’t name the brokers in a column. But it’s possible to unravel which they are. For my own use, I did so for all funds, but I present here only the bonds funds (since this is a bond forum). http://etfdb.com/type/commission-free/all/expenses/sortfield...

Here are the keys: CS= Charles Schwab, ET = E*Trade, FI =Fidelity, FT = Firstrade, IB = Interactive Brokers, TD =TA Ameritrade, VG = Vanguard. Of the brokers, Firsttrade is redundant. Any fund that is available through them is also available elsewhere. OTOH, they might be a viable alternative to Scottrade, whose pricing they seem to be competing with. As yet, I’ve made no attempt to determine execution details like ‘mandatory holding-periods’, ‘permitted market side’, ‘mandatory trade size’, etc. You’re on your own for those, as well as determining the suitability of any of these funds for your own portfolio.
