Christine:
"the canada site shows a 82 to 85 red tristar"
Dave's is different from that one shown on the Canadian TriStar site. Dave's has a two-tone red-and-white bumper, and his also has the cord-winding bracket on the bag door lid. The photo on the TriStar Canada site is the same photo shown on the American TriStar site, but it's available in a larger size on the American site. The larger version shows clearly what's a little hard to see in the smaller one- the white two-speed switch.
So, Dave's has three major differences.
