Ever wanted to own an actual Cyclon? Of course you did, and this might be your best chance. The Official Battlestar Galactica Props and Costumes Auction has a ton of set-used pieces up for grabs.
You can get your nerdy little mitts on costumes, production art, props, set pieces, and other relics from the beloved space opera -- both the original version and the remake, which some normal people actually watched. Guns! Helmets! Life-size gold-plated robots that make people feel awkward when they're in your apartment! [Battlestar Props -- Thanks Adam!]
