PKE Meter - Ghostbusters
By Matty Collector
Yes, this is technically a toy. But the folks at Mattel have done pretty great work with their Matty Collector line of toys for grown-ups. This is an almost perfect replica, that works the same way that the prop did, with lighting patterns accurate to either of the Ghostbusters films selectable based on your preference.
The only real downside is the copyright mumbo-jumbo on the back, but that's going to be the case with any licensed replica. One of these days, I'll get around to sanding it off. Or, if I'm feeling really adventurous, I'll pick up all the parts to build one from a shoe polisher and cannibalize this for the guts.
