I'm new to the site, and have only been trading for the last month. I started with Sharebuilder and am in the process of switching over to Scottrade. I found that Sharebuilder's commissions were much higher than what I was willing to keep paying. Also, when I was purchasing I didn't see the options to do any Limit trades. It helps that with Scottrade, my local branch is across the parking lot from my office.
