Best Download Manager?

Hello there! Currently I'm willing to install mandriva linux but whenever I compare the md5 results I get frustrated. It's the third time it happens. I'm a little bit cheapskate now and I won't buy a Linux inst. CD. Do u guys know a good download manager to use so that the download is sucessful? What download manager do u use? Already tried leechget, flashget and getright but all failed.

wget
there is also a windows version (never tried that one ;) )
http://gnuwin32.sourceforge.net/packages/wget.htm

you could be downloading a bad mirror. happens to me all the time

so where i can find good mirrors? For mandriva limited edition?
