Question about equipment rentals

Hey guys, so I live in the middle of a cornfield in Ohio and I am considering Starlink as an option for internet. My brightspeed dsl isnt holding up to my current usage. As my gf likes to stream movies and tv. I like to game (mostly fps) and my mom likes to stream movies and TV. Ontop of her using her computer that kills my internet because of ad heavy websites. And what not. I think starlink is my magic bullet to fix my issues. But I see for the equipment rental how much is it monthly? And if I were to rent the equipment just to try it out for a month and I like it but decide to buy my own equipment would they allow me to swap equipment for free? Is there fees? Would it make it complicated with support to swap hardware? Just fishing for some answers.
