Analog scopes are still a thing, especially when compared with cheap digital ones that often distort things or flatly don't show them. If one has only 150 bucks to allocate for a scope, unless the digital scope added functions (math, storage, etc) are needed, the best choice is often an used analog one. Digital scopes start to become interesting when they go up in features and price, 12/14 bit ADCs, much higher s/r, high res screens, etc.
