MUD tends to support the enthusiasts, like @reevesci , or @UnderDawg
ARB mass produces things and doesn't give back to the community like the people stated above.
In my opinion you will get a better quality product, with the option to customize things, for roughly the same price as ARB.
And then there is the made in China debate
So to answer your question, I don't know who sells arb stuff around here, haha
If you must have an ARB, wait and keep an eye out in the For Sale section. They come around a lot.
I had one. Like others have mentioned, they are not really worth it. The only downside to buying a roof rack that is not ARB is that they don't let you into the rich part of the Serengeti. . .
