I simply dont trust ETF's. They dont have the metal, they have the right to buy the metal from someone they hope does have it for a certain price. If problems occur you become a general creditor, you can't go get your metal from them. If their counterparty doesn't have the metal and goes belly up they are stuck with nothing.
That's certainly not the case with the major metal ETFs traded in the UK. The metal ETFs certainly do have physical metal in secure vaults, 'allocated' on their behalf, in their name, and subject to daily audit. The metal isn't leased to 'short sellers', nor is it used as collateral against any other dealings.
Anyway, the question was broader than metal investing. ETFs are an excellent way to invest in the broader market. Very low costs, and in most cases own the assets outright (exceptions for the derivative funds, such as the non-metal commodities or leverages/short funds).
I've got quite a proportion of my portfolio in a variety of ETFs - divided roughly equally betwen Euro index tracker, brazil index tracker, Euro govt bonds (not a particularly great income, but some defence against devaluation of the £) and a mixed precious metal ETF. I also hold one managed fund - Blackrock UK absolute alpha - mainly because it's returns are very poorly correlated to the rest of my portfolio.
My ISA is with Iweb - £10 a trade for ETFs and shares. They do funds as well, but I use self trade for funds, because they're much cheaper (selftrade don't charge for managed fund purchases, and give a big discount on the initial charge) - whereas with iweb, you pay the £10 purchase comission and the full initial charge!
