From Neatorama today, the REALLY cool-looking (and pricey) replica of the Lost in Space Laser Pistol:
Sci-Fi Metropolis in collaboration with master propsmith Richard Coyle, created this 1:1 scale model of a laser pistol from the 1960s sci-fi TV series Lost in Space.
We should warn you though ("Danger Will Robinson!"), the limited edition models aren’t not cheap: they go for $600 a pop.
