Yeah, photoprice doesn't include B&H or Adorama refurbs, but they do list B&H used items as an ad above the price list.

As long as we're talking refurbs, also note that Adorama upgrades the warranty to a full year on Canon refurbs, and will even cover the return shipping, from wherever it was originally shipped to, in case of a warranty repair.

And, as long as we're talking about shipping to Canada, does anyone know if LensRentals used items can be shipped to Canada? They tend to have a fair selection and their descriptions of lens conditions are quite detailed, so you know what you'll be getting.
