The rubber has degraded in the harmonic balancer on my B230FT, the timing mark has slipped about 30 degrees and I know it's just a matterof time before the sections separate entirely. I've seen new OEM brand ones available in the $130 range and aftermarket for about half that. Does anyone have experience with the aftermarket versions? Are they worth getting? I've seen some aftermarket parts that are equal or better than OEM, but others are crap. I don't want to get screwed by junk and have to buy another new one but I don't want to spend double on the same thing either.
