Not completly true, U can carry just all high end brands, but u have to make areally good name for urself. A local shop by my house doesnt carry anything below Arc. They have Arc, Morel, DLS, Helix, Brax, RE, ID, Tru Tech, and some other ones I cant think of off the top of my head. They have a really good rep of doing extremely well installs, just u get what u pay for, so they cost alot. But Its a great shop and they carry only high end and they do very well. But than again I live in So Cal, so more people with money.
