I don't have experience with Lyman 45, so I can't diagnose your problems as to the lube leakage. I will let you know that the SAECO unit uses dies and top punches that are unique to that unit. I like the SAECO better than the other two, but that is my preference only. If you are looking into buying a new sizer, and the budget allows, I would take a hard look at the Star sizer. It is superior in every way to any of the other three in all ways with the exception of economy.
