well thanks for all your responses guys
so far my experience is that usenet is good for very large files, such as 10GB x264 movies, especially since you get good speed and there's no hassle with all the links.
I'm pretty picky about what I download so I kinda generally prefer direct dl because there is usually more info about the file and there is quite a bit more hard to find and good quality content available.
Also, there are plenty of large files available in 1GB links on direct dl, so its not that inconvenient. I imagine direct dl is pretty safe because there's no seeding like in torrents and it can and is also used for legit purposes, like usenet.
Concerning uploading, does this guide entail all I that need need to know about usenet or is there more?

and which providers have the best policies?
is it safe to do through free ipv6 lol:whistling?
As far as expense goes, usenet seem like the better deal. The only dl provider that in my opinion might be better is megashares because its cheap, unlimited and has similar content. The problem with paying for direct downloads is that the files that you may want to download are scattered all over different file hosts. I've never payed for anything tho . . .
And finally, how is tehParadox safer than pspiso?
the majority of their uploads are to the same hosting sites - megaupload and rapidshit
