Before you go slagging off alternative methods, the least you could do is try the other methods, have you? I've tried Rapidshare, torrents you name it and all either drag their heels or impose barriers such as timed waits as does Rapidshare. At no point do you need to laboriously piece together all the fragments as they exist on the newsgroups, that's what the NZB file is for. I have never been frustrated, on the converse always amazed at the ease, and has always exercised 100% link speed from go to whoa.
Orrrr diddums, it took at most 30 minutes to set it all up and once it is done it is easy as a 'google' search on a NZB site.
