727 B&M star shifter problems

Need help. I have a 727 that came with a b&m starshifter in my 70 duster. It has been a problem since day one. I've melted one cable even with a heat deflector. It's always hard to get out of park. And today something snapped inside while trying to get out of park.Tranny was rebuilt by a good shop. I'm done w/this one. Any recomendations on a good reliable shifter. Thanks Rick
