Not sure who posted the comment about the 115 mm refractor that was barely good at 30 times per inch and that it would only be good enough possibly to give to a kid starting out? I think that's somewhat foul play considering the probable price difference between that refractor and a Takahashi or a astrophysics or whatever high end you want to swing at it.
Some of us don't have that kind of money. Doubtful that a 'kid' is going to have that kind of money either by the time they have to get the scope, mount,eyepieces etc to make everything work. I definitely don't consider Chinese apochromat refractors low end. Also 30x per inch is on the low end for my eastern scopes, that I do know.
I have never met a refractor that is not a toy and in proper working order that can not muster x50 per inch. Good samples of premium models can get too or near x100 per inch but I only find that useful for close doubles or the Moon on very good nights. And even then mostly just for the fun of it. To paraphrase Al Nagler don't use more magnification than needed to reveal the detail you wish to see.
