Most of my stuff is Redding, but I do have a Dillion 550 that I use quite a bit. My old tumbler is a Lyman 1200 over 20 years old. I'm just wondering if the Dillion warranty extends to electrical products. You might want to check their liability statement. In with the new Lyman tumblers, their giving a one or 2 year backing. In a way, can't blame them, as with power surge's and the like, tumblers are no doubt outsourced by Dillion. Any electrical part you buy from a Radio Shack,Circut City, wherever, if the box has been opened, you can't get your money back. Just a thought. gypsyman
