Best Bank for Solo 401k Accounts

[Bryan O.]

What are some of the best banks to establish 401k accounts in? I originally used TD Ameritrade as recommended by my 401k plan provider, but they have changed over the past couple of years and are excruciating to work with (I just got off my 4th call with more needed tomorrow) just to invest in an LLC. It didn't used to be that way, but now they think that anything that is not buying stocks is a withdrawal from the 401k.
