Dear Harry: I have been seriously considering putting a portion of my investments in gold. I think the gold bugs actually have a weak case in linking gold prices to inflation, but our exploding national debt practically mandates printing more dollars. Even at the current record prices, holding some gold seems prudent as an asset-preserver. I'm not sure of the best way to invest in it. ETFs (exchange-traded funds) charge hefty fees, and I don't like the idea of sleeping on a bunch of gold coins or bars. Bank fees for their vaults are expensive. There is an Internet company that charges minuscule fees for safekeeping that are less than a fifth of 1 percent. Is this too good to be true?
