From the editors
We shop for the same things you do, so a guide here starts with the question you actually have: which one is worth the money, and how do I keep it working once it is home?
That is why the cleaning and care how-tos sit beside the comparisons, and why a pick with a catch has the catch written into it rather than left out.
