I'd say go w/ the Stillen bar. I've heard rumors of others like.. Cusco or something, but never seen them so cant verify their existance...
Other than the Stillen ones, I only know of Japanese ones which wouldnt be to cost effective to get here...
The only thing I dont like about the Stillen one is that the mounting brackets are pretty shitty looking... but powdercoating them will make them look a ton better!!
