Where to buy used

[Alan001]

Hello my question is where who can be trusted when buying a used Rolex online ,will people who do this please suggest some places known for integrity. I live in Canada and far from businesses advertising online within my country if anyone knows decent Canadian merchants please list it ,am also interested in American merchants to deal with . I am concerned with fakes and basket cases and almost paranoid about trusting someone sight unseen in person , any suggestion how to make this transaction while minimizing undesirable results. Thankyou to all who took the time to read this , and to those who can help steer me in the right path to Rolex .
