ARB, Lock Right or Power Trax??

I´ m thinking in buy a locker for my "daily use" FJ-62, and i need to know which is the most advisable?

Thanks, David Altuve.

If your going to use it for daily use and light off-road, and you keep your tires under 33s you might like the power-trax, they are a cheeper way to go, and if you could find one look for an eletric locker off a landcruiser, my fj80 has them and they are pretty cool
