Post #22,
I subscribe to a number of professional magazines & their web sites- you might learn much if you advanced beyond picking up free copies of whatever you are referring to?
For instance, the letter pages of the magazines I refer to are full of technical rants and often video'ed
complaints regarding tools and materials.
Perhaps you had not considered that professional journals have letter's pages?
If you assume that my knowledge is limited to reading adverts in the free magazines handed out at suppliers, you are mistaken.
I misunderstood your use of the term "professional trade journal", I hadn't realised that you meant that you subscribe to over the counter magazines.
That said, I suspect that no other human could amass as much knowledge as you regardless of how many "professional trade journals" they read.
Out of interest, what is, or was, your trade? My bread and butter is decorating but over the years I have worked for cabinetmakers, lift engineers and general builders.
