NYT and WaPo can be had cheaply if you grab them when special offers are available, and then once you do, you'll find that at renewal time, all you need to do is threaten to unsubscribe and they will let you continue at the much, much lower rate, which usually is around $1/month for each.
Talking Points Memo runs me $60/yr, which is a bit steep but I want to support their independent journalism, and the careers of various young journalists that has supported.
The New Yorker is expensive, but again can be had at a steep discount if you time it right, usually for around $5/month if memory serves.
I also support theconversation.com. Its non-peer-review publishing of academic content, with a current-affairs context to most stories. So its like behind-the-news stuff. I say 'non peer review' because the actual articles themselves are just that: not peer reviewed. But they often, if not always, cite peer review work
