This set is fantastic! My wife and I typically build sets on our own, but we decided to do this one together. It was a wonderful building experience. The set is exquisite! The colors are vibrant and the design is very well thought-out. I realize that some feel this set is expensive, but it is actually a work of art and made for display. As an art piece, this set is well worth it!
