I would like to invest in some gold soon, but would rather buy a big lump of pure gold than invest in shares assosiated with gold. where can i get the cheapest price, safest buy?

Any thoughts on Black Rock Gold,which invests primarily in gold company shares?
Their price relative to gold has come down considerably more.In other words,when the price of gold was about $650,there price was about 10. per unit.Now,with the price of gold at about $800. their unit price is just under 9. per unit.(down from a peak of something like 11.50 per unit)
Not a great performance,but might the future suggest a period of out-performance?

Im reading a book at the moment called the bull hunter by Dan Denning that goes into etf's and their trading strategies costs a tenner and published in 2005 so things have moved on a bit since then.I have never traded etf's but they seem to be incredibly popular at the moment for a global, diversified approach with cheaper access than mutual and ability to go long/short etc. . He mentions the american stock exchange has a gold index gdm with 36 companies
