It's not a fair comparison
Scottrade is a full service broker/dealer and has all the products, services of any of the major firms. Sharebuilder is not a full serve B/D and doesnot proivde most of the services of other firms not does it permit one trade in any registered securities, you can only select from their list of registered securities.
You will be much better of with Scottrade. Don;t worry about the differences in fees, the services alone will more than make up for it.
Two ways to move your account
1- Open an account at Scottrade, then liquidate everything at Sharebuilder, take your check and send it to Scofftade
2- Tell Scottrade you need ACATS forms, (may be able to go on-line and print them from Scottrade's site) when you receive them, just sign them and attach the most recent copy of your Sharebuilder statement and send it all to Scottrade, they'll finish the rest.
