Talking about sophisticated equipment (read expensive) for simple jobs, I had to laugh at an "amazing" Led readout box for letting you know when your distributor points opened for setting the timing on your classic car.
It was something like 40 quid ! when a bulb and a bit of wire for nothing will do the same, you can even buy a cheapo multimeter for less than a tenner that will suffice and can be used for loads of other things
