My first choice in dies is always Redding. But I know they are rich for many these days and RCBS is almost as good. But this isn't what you asked, as a general rule, I never choose LEE anything. I have sold them for many many years and by and large the only products that are returned are LEE. Many here like and have had good luck with them. I have probably thirty plus sets of dies, I load allot. I have only ever had one die set fail it was a STD lee carbide 500 set. The carbide ring dinentigrated.
Do your self a favor, buy quality the first time. As a smart man once said the sweetness of a good deal sours with the reality of poor quality becomes apparent.
