CFD trading platforms

Hi all, I am new to this forum and figuring my way around the investment. Does anyone use any CFD trading platforms in New Zealand? I'm thinking of using CMC markets as they seem to be the cheapest but are there any others who provide this service at low cost and better then CMC markets?

Have found Interactive brokers to be great for CFD's, relatively low costs.

CFD's can be a very volatile rough rollercoaster if you are unprepared, how strong is your stomach and how deep is your wallet?
