I agree with Mark.
Auto ranging may have it uses when you are measuring components out of
circuit or stable voltages. A number of tests Elecraft kits require is the
resistance between two points in a circuit without power applied. Using a
manual range setting you will get different readings on different settings
due to how the voltage is applied and how the circuit reacts to it. This
will often confuse autoranging meters.
Therefore the recommendation here is to make sure it will allow manual range
selection.
