I used Monoprice for cabling and for a room full of wall jacks and even after shipping and duty it was still cheaper than anything I could find Canadian. The in wall speakerwire was really nice to work with as well.
In comparison, I bought some Home Depot bulk wiring as well but I never will again. It is anything but flexible and you will need to wear gloves just to not cut yourself when working with the ends. It will tend to break apart and get lodged in your fingers. It also corroded prematurely at the ends. The Monoprice does not show a single hint of discoloration yet.
