The crazy kids at Lego do a pretty good job of giving us interesting items to build, but what if the thing you're lusting after — a Lego DeLorean, for instance — isn't available? That's where these Ichiban Custom Lego Kits ($15-$800) come in. Painstakingly designed, each kit arrives with all the brand-new, official Lego elements needed to recreate the design, but many also arrive with an instruction booklet — otherwise available as a PDF download — and a collector's box. They might lack some of the polish seen on Lego's most impressive kits, but if you're looking to build a replica of the U.S.S. Enterprise, the Batpod, or the Nebuchadnezzar, they're the only game in town.
