I have the cheapest kindle and it's perfectly acceptable. Lasted me three years and no signs of stopping. I know I'm not leading the vanguard by buying from Amazon, but my entire collection of animorphs helps me sleep at night.
The color kindle is anti revolutionary though.
Edit: whatever e reader you go with, grab a book style cover for it. You can find em cheap and it helps a lot with durability and ergonomics (stops it from sliding around your leg).
So I'm an American living in Aus for almost two years. In that time, I have become the token American for friends and strangers alike, an easy target for people who consume a lot of American political news and are looking for someone to practice with. And I'm always down, it's still interesting after all this time to hear an outside perspective.
One thing I rarely hear, however, is that Australia is heading down the same conservative, corporate path that lead to the USs current state. In fact, the media makes Australia seem so much more batshit conservative than any Fox News dude, besides maybe Tucker Carlson.
From what I've seen, Australians have a lot to be worried about, in ways that mirror the downfall of the US. A rapidly rightward marching Overton window, as well as consolidation of conservative power. A heightening of xenophobia that I find much more troubling than anything I'd seen in the US besides immediately post 9/11. An economy based on extraction of depleting resources. A population that finds it extremely easy to tune out activist voices. And let me tell you, many Australians DO NOT want to hear such things from an American, a lesson I learned early.
All this rambling to say the US is a low bar yes, but it should serve as a warning how easy it is to get there, not as an example to laugh at. Australians are a lot closer to Americans than they think. I love yall, but be humble. Also, I'll take all this back if you just process my damn visa... Please...
