Best that I know of (there might be others as good), based on;

Webiress platform provided free for active traders (live data/news, DJ newsfeed, currencies, spot gold, international markets feed etc).
No market making (i.e. no ripping you off).
Direct market access. You see your order hit the screen instantly. No delay at all. Fastest order processing I have seen.
Competitive fees.

Margin on ABU 35%- but be very careful with high margins on volatile stocks.
The best way to utilise high margins is use only a small part of it in normal times and leave the rest as a buffer to avoid margin calls at times of depressed prices. You want to be able to buy on the lows, not be forced to sell.

They are also flexible on rates. They are often willing to add or increase rates on stocks when asked but you may need a period of time with them first.
