Opinions on gem microscope

Could some one please help me. I need a microscope for getting my
GG. I see microscopes for 500 dollars with a zoom of 7 to 45 . Like
the mark X. Is it worth the money or should I go better quality. I
don’t expect to use it a whole lot. I’m a small fry. I don’t want to
buy it and return it.

Thanks Steve
