I have several SDB's and one broke New Years Eve, the lever arm broke on top. I think it was made about Ab Lincon's time , it is a very old machine. Called Dillon and they are sending new parts to fix at no cost to me. Second one too break like that.
Was not a good week as my 550B #7 shell plate also broke. That one cost me $8.50 to ship back to be replaced.
Over the years they rebuilt an SDB that I was given that went through a flood and sat in a outbuilding for a year. That one cost shipping there only.
All I have ever used is Dillon and one single stage RCBS. Don't know if the other presses carry as good a fix/replace polices. I don't fill that customer service is as good as 10 years ago as it never cost me shipping till about 2010. They have changed polices on what carries life time and what will not. Before if it said Dillon it was fixed or replaced free.
