Easy: buying KRE-O Sentinel Prime.
Hard: finding time to put it together without losing any pieces or developing Carpal Tunnel Syndrome.
Crazy: Photographing
every last damn piece in the set and uploading them to shmax.com. This particular kit has over 900,000 pieces, or at least that's probably what it was starting to feel like to Spliffdizzle around part #157. But he hung in there, didn't give up, and--hang on, there are actually still a few parts in the list without photos. What happened, Spliffdizzle? Did the cat did get to a few? Run out of flash cubes? If you've decided to retire from the sport, please signal by uploading another 500 photos.
