Makers’ listings

A-Z, under principal use

This list is not intended nor able to define high performance. At each level, it is common for only arbitrary models made by some of the (e.g. lower budget or more industrial-oriented) makers to come within the category; or for the inclusion of the products of a specific maker to be hotly debated. But businesses are living organisms. It is therefore possible for any maker’s quality to flip either way – to vastly better or worse, at any time. Unlikely in theory, but it has happened. Caveat Emptor!
