Its a little dificalt to say a 'scope' is or isnt good .... It realy depends on what you are trying to do with it.
I have a little single trace handheld digital, its little more than a toy in the greater scheme of things and priced as such but it will just about manage to display a composite video signal and is fast / accurate enough to handle the relativly simple projects I want to play with.
So for me its great because I could afford it and it ticks most of the boxes I need.
In a profecional service or development environment it would be next to useles!!
Prety much any scope will be more use than a meter when yiour learning.
Have fun and dont worry about it untill you find something it wont do for you.
Just my penneth ...
