Such as https://www.dell.com/en-us/shop/dell-laptops/inspiron-15-lap... which is $530 at the moment but you can get it for cheaper during Black Friday. The manual may say up to 32GB but installing 64GB works just fine, as the CPU supports up to 64GB.
For $330, you can get an i5 Lenovo IdeaPad 14" today but it goes up to 36GB only because one of the 4GB RAMs is soldered https://www.microcenter.com/product/666315/lenovo-ideapad-3-...
You can install 64GB RAM to i3 laptops as well, which can be as low as ~$300, for example https://www.dell.com/en-us/shop/dell-laptops/inspiron-15-lap... is currently $350, but you can get a similar one for ~$200 during Black Friday.
64GB RAM in a laptop may cost a fortune in Apple-land, but it's pretty cheap to get for "normal" laptops.
(You can't upgrade RAM with Acer Swift 3, it's soldered.)
