maybe you're not seraching hard enough
i find good ones on h-t and craigslist all the time. but they get sold QUICK!!!
the quality of an aftermarket one is shitty, you're gonna end up with broken tabs anyways with the aftermarket ones, cause its thin and flimsy. also if you didn't know. aftermarket ones dont have the words "INTEGRA" indented on them. btw, these cheap taiwanese bumpers costs only $30 from these shops, the rest is profit.
