I don't have one myself, but do remember them.
They are not very common.
Story has it, that Polaroid had licensed Keystone to market the 60 Second Everflash, a camera that made instant pictures with Polaroid pack films (at the time, usually types 107 and 108), but featured an integral electronic flash (I have one of these - it is not a copy of a Colorpack-type rigid body Polaroid, rather their own rigid-body design, with nary a single part from a Polaroid, and quite heavy. It needs to be manually cocked, and, in flash mode, the aperture is geared to the focus for proper flash exposure).
What follows here is conjecture:
Keystone either assumed that their license would apply to future Polaroid formats, or brazenly ignored the terms of their license and made the Wizard (an "Everflash Pronto" of their own design), knowing their peel-apart camera was at a disadvantage in the marketplace.
I've also read rumors that Keystone didn't even have a license for the 60-second Everflash in the first place, but that Cambridge didn't bother pulling them over as the peel-apart Everflash was not seen as a threat.
In any case, Polaroid did not approve of any competition from the Wizard and was able to get it pulled from the market.
