I am not so luck, I just open an account last week at Etrade and want to buy more SSSU (but my deposit still not availabe to be used to buy SSSU). I am so dissappointed ET is doing the same thing as TDA.
I have a account at TDAmeritrade which restrict me from buying cshd and sssu(I am luck I bought sssu before they put a restriction, and now I will hold it until $0.30 per share).
