Yeah, switch. That's what I did. I am with Scottrade now and just waiting on my Sharebuilder stuff to transfer over. I also had no idea that I could not buy this with Sharebuilder until I tried. That was when the stock was at $1.80 and if I could have purchased then I would have 2 to 3 times what I have now.
The reason that I went with Scottrade is because my father recently opened an account and really likes it. He also referred me and we both got 3 free trades. The only thing is that you cannot do an express funded trade like you can with Sharebuilder but the $7 trades are nice.
