"Sharebuilder is not great but offers $4 market order investments every
tuesday if put in by Monday. The site is overall a B- and takes time
to place a trade but you get what you pay for and if you are just
looking for a investment every now and then and want to cut down fees
the $4 automnatic investment plan is cool."

"The only good thing about sharebuilder is the express funding feature.
You can buy instantly for an extra 5 bucks and it will take the money
from your bank account. THAT IS IT. Other than that sharebuilder is
garbage. Don't use it as your main brokerage. I use zecco and love it.
4.50 trades, NO EXCEPTIONS. Whether its penny stocks or 50,000 shares
its $4.50 per trade."

how do you know the sharebuilder doesnt do the arbitrage for you and zecco against you. i make big trades and i'd rather pay $20 than $4 to ensure that the broker gets me a better price--that arbitrage of 10 cents a share times 200 shares erases the difference in commision
