Yeah the shipping certainly is the killer and particularly so should you have a warranty issue and have to return the bit of gear at your cost.
For items like a CM (or Hornady's equivalent) I would price up from Jason @ Ozark Outdoors first. He also trades as Ozark1 on TM.
As for tuning CMs there is lots of info on the web now. Originally it was a guy on a South African forum that posted the codes. Here is one site Speed Up Your RCBS ChargeMaster within AccurateShooter.com with mention of Jaco Brink and hisfull list of codes.
