Pitman Arm Differences

[65 C20]

I have a 65 C20 with a 283, 4 speed that I am going over to power steering.
I have a P/S box from a 70 C10

I have a friend in Indio CA. so I phoned a few places there for a pitman arm there and the prices vary alot.
Moog $131.00
Raybestos $96.00
Moog secondary $24.00
Auto Zone brand $32.00

My question is are Moog that much better or is it a question of you get what you pay for ?

In Comox here I was quoted $140.00 for a Moog.

Thanks for your input.
Cal.
