while i had my scottrade account i was never even able to get the quotes to work. so i got medved qt for quotes. switched to rushtrade they have a direct access program thats free or $50 a month, its not fancy but it gets the job done. if your looking to take a step up from scottrade consider rush. http://www.rushtrade.com/
MB was recommended to me, but I haven't used this because they don't offer enough financial instruments for me, but they may work for you.
