Sorry to say it BM, but thats another crap argument!
There is a HUGE difference in quality , looks, features between unbranded 'Ripspeed' units and braded, JVC, Alpine, Nakamichi etc... units... In some cases with body parts the unbranded parts look the same and do the same job, and im some cases even fit as well, so i dont think that pitching the argument in those terms really works in this case.
