Boy, isn't that the truth. I have found that the attention to details, like final polishing, are something I need to check on even the better dies. I've found that drilling out a case head and cramming an old brush in them then coating them and spinning them up with a cordless electric drill motor set to low speed works good. I use 800 grit lapping compound (only on really rough ones) followed by Flitz and that has worked well for me. Just Flitz makes a big difference on most though.
