Sharky has put a list of regulated brokers in the tools section at the top of the T2W pages. I know I keep banging on about this, but it's got to be the safest way to start any research. The problem with googling for same is that a lot of them are not independent or impartial, and may well lead to non regulated brokers and bucket shops.
It's a simple first rule: only ever deal with a regulated business.
