I got these controllers in the other day from a Spanish seller:
While the Zinger looks like the unlicensed Beeshu Zinger (I have a loose one of these) given the packaging, it turns out that it's actually not the official unlicensed Beeshu release (no Beeshu on packaging, and while the packaging is in the unlicensed Beeshu style, the unlicensed Beeshu Zingers have a different joystick mold, and this one has the mold of the licensed Zinger...also, unlicensed Beeshu controllers have a Beeshu endconnector, licensed ones have a black Nintendo endconnector, yet this one has a plain grey one without any logo...same goes for the Beeshu Zoomer-clone).
I'm assuming these came from Talent Electronics, as they released at least a Beeshu Zipper-clone in Famicom format (and are linked to a GBC release of a Beeshu Zipper-clone in NES format), and the product code type of the Zinger (VG ###) is just like that of the other accessories related to Talent Electronics. I have a hunch there may also be an Ultimate Superstick clone out there, because there seems to be a relationship between Marpes and Talent Electronics (in more ways than one), as Marpes is still selling the Commodore version of this same Zoomer-clone (check one of the following pics, the box is universal and there's a checkbox for the Commodore version on the side of the box) and also an Atari version of an Ultimate Superstick clone.
Also, might be interesting to know that there's at least one more Zoomer clone out there for the NES...instead of Zoomer or Joystick in the center of the controller, there's a sticker with something along the lines of "Para......." (I've seen the controller with NES connector but was unable to make out the full name on the sticker).
