LEGO Star Wars TM Captain Rex's AT-TE? 75157

I did a lot of comparison shopping and was surprised that Walmart's price was far less then all the others. The Lego set itself is a great gift because it's a project which with almost a thousand pieces I thought would keep my nephew busy for days not hours but I was wrong. However, I think most youngsters will be challenged with it for several days putting it together. It also has so many features to it that once put together it becomes a toy that can be played with and not just added to the shelf collection.
