Detroit axle wheel hubs

Looking at option to replace a noisy front wheel hub bearing assemble on an Old Aurora and came across these. My understanding is detroit axle is a solid company which makes these parts but the price is less than half of comparable impatiens. Has anybody used replacements parts from them? Are they worth it?

Mine came from Champion (now Oreily) for somewhere over $100 and they have been fine. I would just get them from a reputable parts place like NAPA and be done with it. How can you tell the hardening qualities of a chinese bearing?
