Try Flash Get or Free Download Manager (FDM).
but
for downloading torrent:
My recommendation is u should use utorrent instead of download manager, because during download of any torrent (for example torrent of movie dvd or iso file) with utorrent, your computer shut down due to electricity failure or due to any reason.And now your 40% file is damage, but with utorrent you can again start torrent above 60% but not from 1%.
If you were downloading with any download manager with resume facility and your pc shut down due to any reason, before pc shutdown you downloaded 60% file, but when pc start you have to again start download from 1% because your file are now corrupt and resume will also not work.
