As a veteran, I love me some "built in the USA" stuff, but I have heard that the Chinese light bars are not that bad when it comes to quality. Haven't owned one personally though... I do know that the prices have plummeted on eBay. Maybe supply is greater than demand? Looks like everyone jumped on the LED light bar bandwagon all at once.
The biggest downside with the Chinese import light bars are the shoddy optics used for projecting light. A while back I was parked side by side with my buddy who installed some cheapie 20" bar from Rogue 4. It was bright, but looking at the light projected out there were hot and cold spots all over the place where it was projecting light. In comparison, my Baja Designs light bar was smooth and consistent everywhere light was projected.
Essentially you get what you pay for. If it's cheap, it's cheap for a reason. That said though, if you're just looking to put a light bar on the truck for looks, buy whatever you want. If you're putting it on the truck because you'll have to depend on it when you're using it, pony up and get a quality light bar. My vote is for Baja Designs, VisionX or Rigid
Baja Designs: Made in USA with components sourced from domestic and foreign sources.
VisionX: Made in South Korea I believe.
Rigid Industries: Made in USA with components sourced from domestic and foreign sources.
