I got some good advice for buying instruments from a music teacher. He advocated buying a decent instrument especially for beginners.
A "beginner level" one is harder to play nicely and frequently destroys interest. A decent one keeps a higher resale value. Once you reached advanced level (and sometimes beyond)you got a decent instrument you are used to.
The only reason I have a Hohner Happy Color harp is because it came in a set with book and DVD. The instructor on the DVD plays a decent blues harp. Good luck trying to match the "it should sound like this".
