One of the best downloader that i have been using so far is Jdownloader. It is a java applet that lets you have multiple downloads and manage them with ease. And this program lets you download files from megaupload, raidshare, hotfile, fileserve, etc... without being bothered entering captcha codes. It is really easy to use and without the worry of entering codes and for those who have premium memberships with those downloading host don't need to enter codes and can download in their full speed. There are much better ways to use this application and it also downloads youtube videos by just copying the link of the youtube video and jdownloader automatically detects it and just choose whichever you want to download either the high quality or the lower one or just simply the mp3 version.
There has been a lot of download managers but i am choosing jdownloader to be the most reliable download manager.
