I keep hearing good things about Automatontoys. I always mean to buy from them, but I live and work in Vancouver and Richmond, so there's plenty of places to stop on my commute and pick up imported items at reasonable prices.
However, more Canadian competition would be appreciated, especially since the unfortunate, recent demise of one particular Canadian retailer in both online, and brick and mortar. I am refraining from saying the name, since I don't want to trigger any nasty flashbacks for some people. heh.
