I have been a customer with goldmoney for over 3 years now. I have found them easy to deal with and never really had a problem. There is information on the ownership rights of the gold here: [broken link removed]
The reason I chose them is their cost of doing business, ease of use, ability to make transfers to others in gold.
Before you buy gold you should realise that it isn't really an investment, but more a way of preserving wealth. A gold investment would be more down the lines of gold mining and/or minting.
Horusd has already pointed to some good threads here on AAM, and I would strongly recommend that you fully understand what you are doing before you separate with your money.
