I've been a very happy BAH user for a couple of years now for all the same reasons you've outlined in your post. Mostly though, the ability to buy (or sell) unlimited stocks for a set fee and my investing style ("drip") are what I find most attractive. There are some stocks that BAH does not offer and because of that I've been reading through the information at Sharebuilder trying to decide if I should also open an account with them. Your post has given me some info which wasn't all that clear to me even after reading Sharebuilder's FAQs over and over again. Simply put, I've decided not to go with Sharebuilder. Thanks for the info.
