FWIW I really like Fidelity. That's where all my CGFIA is. The flat fee is nice (7.99/trade) and I can get over only being allowed to buy/sell in 9,999,999 blocks. No idea how it performs with an r/s though. This will be a first. Good luck though. Also though, IMO scottrade has a better platform. All depends on what matters to you. There area lot of platforms out there...
