I am heavily invested at Claymore in the gold & silver bullion ETFs.
These two Claymore funds, CGL & SVR.UN, are hedged US$ which makes them superior to any others in my view being Canadian.
They are fully supported with allocated bullions stored at Scotia Mocatta in Toronto & NY . I have talked to the VP when there was a false rumor circulating about the vault. He goes in the vault regularly to double check the audit. All seems in order and I now trust the E&Y audit shown on the site.
You can view the list at : http://www.claymoreinvestments.ca/en/commodities/
The silver units have not been converted yet to an ETF, but will if it trades at -2% for a # of days . The NAV is now around 2 % above market price so it's possibly a good time to buy.
Good luck
