I've been researhcing reloaders for several weeks and despite recommendations to start with a 550, I had planned to pick a new 650 from gunstop in the next few weeks. Those plans changed today when I found a used 550b on THR for 75% the cost of new. I figure I can learn on this and if I want to upgrade, I can sell for near what I paid.
Besides the usual accessories such as aluminum handle, strong mount, bullet and case trays, it comes with caliber conversion kits (and tool heads/powder dies) for .357,.45acp,.44, and 10mm. These are all calibers I had planned to load. No dies, I will have to purchase those separately.
I'm looking forward to a new winter hobby.
