I don't know how it compares in Canada (I'm in Australia) but when I looked at buying a 441 clone from China I found the prices were very good but by the time I added on all the other costs - shipping, duties, taxes, various handling costs, broker fees etc - there were no savings to be made, the cost was the same as buying one here. And shipping-wise we are closer to China than Canada is!
Plus any guarantee/warranty is also pretty useless, you'll be basically on your own.
