I own one, but have never used it for card to box. As such, I am a little cautious about recommending it too strongly! However, it's relatively cheap, looks nice (sufficiently unusual to be attractive, without looking prop-like) and has had a lot of praise from some knowledgeable people.
Also, I think there's a DVD and book by Allen Zingg on this prop.
If someone can heartily recommend a great box for the specific effect you're after, then please do go with that.
