I was not aware that Ed Brown made an external extractor.
FWIW, I would let the factory do the job for that price.
To change to a different brand of extractor may incur costs that could exceed that $130.
(Of course, you only load using a magazine. You never try to force the extractor over the rim of a cartridge in chamber.)
