Sharebuilder Review

"Investment Plan" buys for only $4.00 a pop.  Great for starters, but one should build up their money in the "Money Market" account before placing a trade.  Buying one share of stock at a time at $4.00 translates into $400.00 commission on 100 share blocks. 

They started charging for "enhanced" services a year or so ago that used to be free, but you can still have a "basic" account with no monthly fees. 

Margin rates upwards of 11% can cut deep into profits if you are not careful.  They also do not allow you to buy all stocks available.  If they don't like a stock, you can't buy it.  Investment "tools" could be a lot better, too.
