Who ACTUALLY manufactures their own jaw crusher???

While looking for crushers, wayyy overpriced to begin with, I started noticing that some "sticker" badged brands look exactly the same as the Chinese stickered ones. The housings on either the faces or the corners have all the same curves, gussets, mounting area and whatever else...but some say Terex, to KPI, Symons so on and so forth named brand ones are better/different, than the way cheaper Chinese stickered ones. What's the deal here?? Are they actually the same ones just different stickers and paint scheme? Who actually makes the jaws and replacement parts for them? They all look the same. I really hope somebody can give me some actual factual info. A side example of such....looking for hot water pressure washers, found Mi-T-M, found out they actually make John Deere's washer...different (gold enlaced green paint) paint and $1000 more on price. It's JD, so it's gotta be better than the actual company that makes it for them...right?!?! :D
