I'm an amateur baker and I've been using a Hamilton Beach stand mixer. I was facing the same dilemma of 'do I really need to cough up for a KitchenAid??'. I had seen the brand in some lists of best stand mixers, and after doing more research on the brand, I found out that they were a legit American company. What ultimately convinced me was reading a review that said "The KitchenAid is a fantastic beast of a stand mixer, but after using this, I tell people that if you need a KitchenAid, you already know it, and if you don't know that you need one, I'd purchase one of these."
So far I've used it for bread dough, meringues and whipped cream, they all turned out fine. I'm quite happy with it.
I would be wary of the Kealife mixer you linked as it seems like it's from an unknown Chinese company with no track record. Not sure what you would do about warranty issues either. And quite frankly, I wouldn't trust random small brands for things which could be fire hazards, which a high-wattage appliance could be. I can't be sure that they actually adhered to safety standards when manufacturing them.
This Hamilton Beach standing mixer is only $75.99 on amazon and has some pretty good reviews for being a budget mixer. Its bowl size is a little smaller though.
