Giganews is great, but it’s usually way too expensive for most people’s service requirements.
For a block account - i.e something where you buy a block of bandwidth (usually a multiple of Gigabytes) which allows you to download what you like when you like, without a monthly limit or subscription charge - you might try [B]http://www.news.astraweb.com[/B] or [B]http://www.usenet-news.net[/B]
Usenet-news is a little bit more expensive, but has longer retention than astraweb at 70 days (though Astraweb still downloads out to 35 days, despite saying it only has 25 days of binaries on the servers). Usenet-news also has SSL access on its european server, if you’ve got a binary downloader which supports it.
At Astraweb there’s the option of taking an ‘unlimited’ download account. I’d [B][U]strongly[/U][/B] advise against this, as it has its bandwidth traffic-shaped - although, there’s no mention of this fact on the site. The block accounts [B][I]do not[/I][/B] have this hampering.
And for the record, I’ve used all 3 and found the block account places to offer the best price/download abilities, unless you have an uncapped VERY high speed internet connection, and mountains of disk space to store things on.
But don’t forget to check if your ISP already has usenet server access. You might save yourself a load of cash, if you find it meets your needs.
If you still decide to go for a paid service, you can usually augment your downloading bandwidth by offsetting some of the download threads to your ISP’s usenet server (have a look in your binary newsreader’s settings to check if you can run more than one server concurrently).
Once you use usenet to grab binary files, you’ll never look back.
