Need to replace the outer tie rods. Is Moog the only way to go? Seen some of the cheaper ones for around $15ea, while moog are a full $40.

 

depends on how much you like working on your car and how much work needs to be done.
back before I had my first 3rd gen I had a cherokee that needed a complete front end, generic was about 1/3rd the price of moog. I did generic figuring I can do it 3x before the cost caught up to me.
in the end I sold the cherokee and kept the max, I don't regret that decision for 1 second.
