If I was eight years old and had a few thousand dollars burning a hole in my pocket, this is how I would spend it. The link leads to an Ebay auction for an "authentic" Ghostbusters proton pack. This would have been the coolest thing in the world for me circa 1987 or so.

The designer spent over a year on it. Along with 35 lb. pack covered in lights and various doo-dads, he’s included a detailed jumpsuit and a specially designed walky-talky with audio excerpts from the movie. Right now, with three days remaining, the current bid is hovering around the $2K mark.
