Suretrade was bought out by Quick&Reilly. Now they charge me almost $20/trade. Needless to say I haven't traded since they took over.
Although I haven't opened an account with them, ShareBuilder looks interesting. They charge $4/trade or $12/month for unlimited trades, but they only make your trade during a certain time period during the day. They really push long term investing. No minimum balance to open.
Datek has $9.99/trades. I have recently looked at them, and they seem pretty good. They have several neat tools. No minimum balance to open.
