if you do a search you'll see a ton of threads where folks debate OEM or aftermarket. i'm not going to speak for everyone, but it seems like when people go aftermarket its to save a few $$$ which there's nothing wrong with. for those that go OEM, its usually because of the critical nature the LBJ plays in the front suspension and that while aftermarket is cheaper, its only about $200+ for a new set and all the hardware for OEM. when i did mine last summer i went OEM for those reasons and got em from Camelback Toyota.
