I recently opened a sharebuilder account. So far so good. I don't have a whole lot money to throw in the market right now, but at $4 a trade for the basic investment plan, it makes it affordable to everybody. I took advantage of an offer to get $25 for free after I signed up and made my first trade. If I recommend the site to others while signed into the website, I can also get up to 25 free trades. Good online broker, I would recommend.
