You know, the problem is, we can have all the top range instruments, oscilloscope, spectrum analyser, logic analyser, signal analyser etc.... but when it comes to repair works, to answer the question, "Are you oscillating?", nothing beats the simple digital logic probe. No need to wait for the instrument to start-up, and the noisy fan whirling noises. Fast, simple and good and no nonsense. Will you turn on those instruments? Many times, I would not.
Also, I am of the opinion that it is not the simple electronic inside and then DIY kid sets.... I would advise beginners to avoid that... The important is the ergonomics of the casing or housing on the hand. It must come with a casing or housing. [Edit: The money is on the casing or housing]
Cursory browse on ebay will review that those slim styled ergonomically designed probes are of those branded brand types and normally higher in price tag. Before you buy though, it would be an added bonus if it will also work with 3.3v power supply level, preferably.
I would change the cheap crocodile style power clips which are prone to short out adjacent pins to those claw or grippers type, so beginners beware of locating appropriate hook up locations.
Will you need to have one?, Yes, in my opinion.
