Harbor Freight has *some* good deals, but if you're buying Princess Auto and comparing (quality / price) - there's very few differences by the time you include currency exchange and potential duty / taxes coming back across the border (if over your allowable limit).
If it's a blended trip of doing other things, its worth going to look if there's one near where you are going. They also advertise in Circle Track Magazine what sale items are currently 'specials'.
In general terms quality vs. quality, princess auto seems to the a slight edge...
Where Harbor Freight has an edge, is what Streetstocker stated, fabrication tools to choose from.
