I have to disagree strongly with this. I started with TN and the commissions ate me alive when starting out with small shares. If you start trading with 200 shares, you need to make 15 cents on the trade to BREAK EVEN. I was hemorrhaging money into the TN coffers. Since moving to IB a few months ago, I am a little bit up. With 200 shares, I only need to make 2 cents to break even. And when you move over 500 shares, you only need 1 cent to break even.
If you are already trading 1k+ shares though, I would say TN should be on your short list. Heck, when I start trading that kind of size, I will consider going back to TN.
