Quote from kentraderstar:
AMP has a good support? Is that a joke? I had the worst support. Some of the brokers do not know what OCO order is.
I've heard similar reports, but as killingtheta said it may just vary depending on the individual broker you get.
I trade primarily E-mini S&P 500 with Cannon Trading, though I do also dabble in some energies, metals and a few others. I'm paying $5 per round turn, then with exchange fees it's about $10/ round turn total... $50 is ridiculous, you should run for the hills after seeing that. I'd really just start contacting different brokers via phone, for example you might be able to get a lower price from cannon depending on your volume and level of broker assistance.

Cannon's been around for decades so all of the brokers I've spoken with are seriously knowledgeable, which I think is vital for somebody like you who is just getting into the market. My broker is actually an ex-floor trader, it's pretty cool hearing his experiences. They also offer a lot more platforms... but this might not matter if you've already chosen one.
Of course, if you are overwhelmingly concerned with the absolute lowest price then IB is most likely where you should go. But as you've seen if you've spent time on this forum, you'll get what you pay for in terms of service (crap), so it depends on where your priorities lay.
The top 5 I would check out in this order:
1.) Cannon Trading
2.) IB
3.) OptionsXPress
4.) Mirus Futures
5.) Velocity Futures
