I've looked at both King and Canwood. Aside from the fence, parts look
similar (if not identical) to those used by General International.
Although they are less expensive than a similarly configured GI, they
have fences that are no doubt inferior to the General "T" fence. I
considered ordering a King w/o a fence, but was told I'd only save
myself CDN$45 (yet the fence is apparently sold separate for CDN$145).
In the case of King, availability is also an issue. Our local Home
Building Center retails King, but since they sell so few units they
can't afford to ship in a specific model from Montreal.
AFAIK, Canwood is only available through House of Tools. I haven't
looked closely at Canwood since the staff at HoT don't seem overly fond
of them.
