What's the best online trading company?

I wanted to know which online stock trading company is better and have no maintenence fees and no account minimums. I have heard a lot about sharebuilder but I am not sure whether it is the best available.

I've only used etrade in the past. Their GUI & tools were very good. However, you'd have to shop around at the various firms to compare prices, etc.

CNN Money Magazine has run downs of the various features & services from those online trading companies, or Yahoo Finance, or MSN Money, etc.

Try Genesis (http://www.gndt.com). They are great and cheap
You can message me and can give you my sales rep - he is really good.
