There's another factor here, too: factory support...and if you don't think a high-end manufacturer like Gobi can fuck up, read the following.
When I bought a Stealth for my LJ, Gobi dropped the ball on the order and took 14 weeks to deliver instead of the promised 6. I have all the sympathy in the world for production delays - especially when a company is growing - but when I was on the phone with them weekly after Week 6 due to an upcoming trip that we needed the rack to complete, I started getting a little nervous. They finally delivered in Week 14 - four days before we left for the trip - but the rack was so hurriedly-built that it was misaligned in the jigs when it was welded, and the paint was still curing when it was palleted and shipped. Result: I had to return pieces of the rack and have new ones shipped in after we got back from the trip, because the rack literally could not be squared up to the Jeep...and it was rusting due to the slipshod painting. I also had about thirty percent of the fasteners gall up on me during removal because they used a lower-quality stainless hardware set that was threaded poorly and extremely prone to seizing...so I had to replace all of those on my dime. Same with the frame tie-in's on the rear: those had to be re-powdercoated, and I had to make heavier bracing plates because the ones they sent were from an annealed steel. The list of issues was actually pretty long, and for what I paid for a rack with all of the trimmings, I was furious. Now, Gobi did make things right in the end: it took a lot of pictures and me showing them exactly what the issues were from several angles, but if I hadn't bought that rack directly from them I would have been fucked...but I did buy from them, and they took care of the customer, and that is commendable.
Moral of the story: on big-ticket items like this, don't cheap out.
