Usenet.net has been providing Usenet newsgroup access since 2004. During my testing I was very pleased to see that they have transfer speeds, article retention and article completion that is close to that of some of the Tier-1 providers I have reviewed in the past.
As an added bonus, Usenet.net has set up special pricing for my users. You can get their top of the line Secure account for only $9.99 per month for the life of your account.

Features

• 24 Hour customer support
• Days Retention
  
• Unlimited speed downloads - transfers from them hit MY limit on my internet connection.
• they do not track what articles you download from their servers
• they do not track what newsgroups you access
• 256-bit SSL encryption is available as part of their Secure account
• 15 or 30 connections depending on if you select the Value or Secure accounts
• alternate ports available in case your ISP blocks or rate-limits the standard NNTP port
• redundant server farms in the US, Europe and Asia

There are some things about their service which might be a concern to some users. However, none of them really detract from the quality of the service.

• they do not allow users to Post articles - many users never post an article to usenet
• users have to provide their own newsgroup reader and binary support applications - 24 hour support is available to help users
