I have dealt with Hornady and RCBS in the past and found both their customer service awesome.
With RCBS I have an old priming station that I had lost the small and large primer rods, I called them one night (during night shift) and advised them that I had lost them and if I could buy them as replacements as I couldnt find the parts on their website. The guy on the phone wouldnt let me buy them and he sent them out via mail to australia free of charge.
With Hornady LnL the primer slides have dinky little wheels on them and they have a habit of popping off as they are only glued in, when I first assembed the press it happened and I couldnt find the pin, called them and advised what had happened and they sent a new assembly out no charge, the same thing happened the other month and emailed them, they sent out another one lickety split. Why they havent developed a better system its beyond me, however their service is damn good.
If I had to got through the aussie distrubutor I would have to wait upto 6 months because they would only get the parts in when they do their orders.
You guys have no idea how good you have it.
