Product review (5 stars): Good Replacement Parts
I overloaded my washer with a king sized comforter and stripped the agitator gears.  I thought I might have to buy a new washer, but after doing a little research on Amazon and YouTube, I realized I could fix the problem myself and did for less than $12.  A year later, the washer is still doing great.  I think the replacement parts are well made and essentially equivalent to the original parts.  I would highly recommend this gear set.
