I agree, Orwell accused Huxley of ripping of Zamyatin and admitted that he was going to base his 1984 on We. I actually discovered it due to writing about Bentham's Panopticon.
Slightly less good but equally important is Jack London's The Iron Heel. Another big influence on the famous dystopian books. Also We is now out of copyright so you can find it for free/cheap. My copy has a futurist cover and a bunch of essays at the end, I think it was only a couple of quid.
