It may not put the fear of the Empire into any nearby planets, but steaks and chicken thighs should begin quivering at Bryan Tate's custom Death Star grill. Currently up for auction on eBay, the grill has a vent built into the weapon-dish and a neat little Imperial Cruiser handle.
Bryan took two Weber grills, painting the inside with Krylon barbecue paint for heat-resistance and the outside with grey engine enamel. The vent on the top opens up and was custom-made, plus there's a second vent underneath.
The auction ends on June 14th, and as of writing is just over $100 (having not met the reserve). Be warned, though, shipping the grill is going to add significantly to that: after all, it's 36lbs in weight.
