FWIW, when I started trading, I've always used optionsxpress. I started off with penny stocks and the commission was HIGH for the million share buys, etc. So I talked to their customer service and right then, they lowered my commission to any stock @ any amount of shares for 9.95 per trade. So I stayed with them. They've never restricted buying of a security either.
I'll first give them the chance to lower my options commissions before making a switch. Their customer service is really good.
