When my ISP dumped newsgroups, I tried some free & paid options and thought
I'd mention that I've had good luck with Newsguy.

They added a new "Mini" account, 6 months of service for $12, that may be a
worth a look if you're shopping for a provider.

Full newsgroup access (text & binary), no missing postings, NNTP & Web
access, 3GB monthly downloads, unused GB roll over, newsgroup search engine
& free SSL.

They have a free trial so you can try them before buying an account.
