I suspect they're all made by the same company and re-branded for distribution. Though I'm not sure.
If the shape of the compressor body is the same, and the gun is the same, then yes, that very likely is the case. "The Sugar Art" is the company that manufactures the Pegasus Airbrush, but that's just their default branding. If you call them up and tell them to rebrand them, and you order enough, they'll do it.
