I looked into creating a "kit" with the CoAx. With the press running about $300 and then adding a scale, hand priming tool, powder measure, funnel, deburring kit, etc I think I will be at about $600.
When I compare that to the rock chucked supreme master kit with the $50 rebate it become hard to justify that cost for a starter kit. All in that puts me at $250. I think I'm going to go with the Rock Chucker and in the unlikely case I need more than what that gives me purchase the Co-Ax later. By then I'll have some experience and understanding of what I need.
If you could drive up to Owego, NY I would show you how to use my equipment so you could make an informed choice.
Are the Rockchuckers of today the same quality as the Rockchuckers of yester-year? There was a recent manufacturing period where quality slipped and lots of on-line dialog about the castings being made in China.
One really nice feature with the Lee Classic Cast is the center bore in the ram that drops primers out the bottom. I don't think RCBS has incorporated that feature in their presses.
