I don't have any firsthand experience with the Trail Gear arms but I have heard about fitment issues with them. The KONGS arms don't sound like a good option for you either if you want to use FJ80 tie rod ends. Personally I like OTT arms, but they are more expensive than other options out there. Sky's stuff is cheap, but they seem to release product and refine later based on the number of revisions to their arms. I would save up for the Marlin's if I were you or just keep waiting until a good deal comes up for Marlin, All-Pro, OTT, or FROR arms.
