I've literally used nearly every reloading press available in the last 30 years. What do I use now? The new Lee Classic Cast press. It handles all loading tasks better than any other I've used, including priming. Is the CoAx a good press? Yes, it is. Is it needed to load for top accuracy? No way. Most benchresters use hand dies anyway. If you load with a press, use the one that is most convenient. To me the CoAx is not as convenient as several others and costs a heck of a lot more.
I look for a few features
1)strength ( a reloading press needn't be as strong as some might expect)
2) alignment
3)good priming and catching all the spent primers
4)ease of use
The Lee Classic Cast fills the bill better than anything I've used yet. That includes the CoAx, RockChucker, Orange Crusher, Boss and 007, and many, many others. You can spend $200 on a press if it makes you feel better, but you're not getting a thing. I'll stack my loads up against anyone's loaded with ANY press. There's a lot of BS being put out about reloading presses in advertising and forums. Don't believe it, use your own head and choose wisely. If you've got the $200 to waste and like the CoAx then go for it.
