Indeed, Richard Lee did disparage a major reloading company by name.
There's a very valid reason the term "Lee-menting" was coined. Considering all that has been written about Lee moulds, it shouldn't surprise a purchaser that its quality and performance may be lacking. I own and use Lee moulds, and may well buy more, but I did so, and will do so with the knowledge that post production quality control work will be required.
There are many reasons why a mould sells for $20, while a mould of similar features sells for $80.
