Most people don't like buying crappy parts and having to change them out 2 or 3 times as often, even if they are cheaper. I certainly wouldn't want to be changing my ZJ tie rod every year because it wears out when I can spend more and get a better quality part that lasts 3+ years. I still don't get people's fascination with Moog either. There's a reason cheap auto parts stores sell Moog as premium and all my economy parts at napa use basically the same numbers.
I bought Moog parts initially when I did the ZJ up grade. They lasted about 3 years. I bought them of the NET, I can't remember where they came from. I have bought from ZJ steering components form other places and they are all about the same. The last ZJ steering parts I got from Auto Zone and it has been over a year. In the last years I have bought items form Orielys and AutoZone and have had to return a tie rod end, and leaky stabilizer for the Jeep and a couple items for my truck. I give them a phone number and they return or refund no questions asked.
There are a couple NAPA in my area and they sell the same stuff as AutoZone or Orielys but for more money, less warranty and since they are franchises they won't get parts from other stores and you have to wait longer.
Tie rod ends and quick and easy to change. I doubt you will find many any better than the other. If you want or need something better buy a currie setup or something similar.
