99 Honda Civic - Best Catalytic Converter???
 

Mechanic wants 1000$ to replace my CC. I am looking online and just wonder if there's any difference among brands. CATCO, Magnaflo, Bosal, Eastern, etc. Prices vary from 107-400+































Any help is appreciated. I think I'd rather buy one online and have the mech replace it than go w/ the one they procure.
