This is about as cheap as you can get Unlimited Internet. Privado is an okay VPN provider that lots of Usenet providers use, fine for browsing or torrenting but not so great for circumventiong geo-blocking or getting regional pricing deal (likely to be blocked).
One thing that sets Easynews apart is that, in addition to NNTP Usenet (ie requiring a special client), they also have a Web based front end with searching enable (including inside archives), so, for instance, you can track down a copy of a particular music single in flac format). The web interface is here: https://members.easynews.com/global5/
I have been using an Easynews $3 USD a month plan for the last 3 years and would recommend them, unless you want to do a lot of posting (they sin bin you if you get DMCAed). Also note that historically Usenet providers offer discounted pricing around Black Freitag / Cyber Monday.
