brokerage - best value provider?

I currently use COMSEC.

I get charged around $50 for a 20k trade.
I did over 350 trades last quarter and still the brokerage remains the same.

Pro's

- For this, I get a real time trading platform for free, that usually costs $70 a month
- Don't usually have any troubles with Comsec live platform
- Get a t+1 daytrade opportunity
- 25% above your holdings trading power credit (however still needs to be settled in t+3)

Con's

- Offers no reduction on brokerage if you trade over a certain amount, like other brokerage houses
- IF you have troubles getting through the help lines takes like 25 minutes.

Anyone offer a better alternitive?? with a stable live trading platform, and reduced brokerage for trading. Currently Looking at Etrade that has 21.95 trades for up to 20k for over 21trades.

Thanks for your feedback
