You'd still pay $200 for this set at LEGO, so this is a good deal. It's also the best price we've ever seen. As pricier sets go, it's also good value since you can build it in three different styles: the original time machine, the Mr. Fusion version from Back to the Future Part II, and the Ol' West version from Part III.
