I don't recall ever seeing the 4056. If I had, I would have bought it for my daughters. So, I'm going to guess it has not been released in Canada. But there is the 5873, which kind of looks like a scaled down version of it.
I don't remember how much the 3019 cost, but it was probably comparable to the 5100 Mansion in price. Does anyone remember how much that was? I'm guessing around $200 to $250, considering the price of the 4250 at $169 in Canada currently.
I have two of the 3019's and they are fantastic.
