I'm a Lego builder and an admirer of historic architecture. I've always found the LDS temples to be quite remarkable. A friend tipped me off to these sets and I had a great time putting them together. They feel and connect together just like classic Legos. A pretty generous amount of extra pieces, as well. You also can't argue with that Buy One Get One Half Off promotion, either. I'm especially looking forward to getting the D.C. temple if it goes back in stock, since that's about a mile away from me!
