You can use remote uploads from Megaupload, to Rapidshare. You don't need a premium account for MU to RS, not sure about any other file hosts.
Make a free RS account, and it's a good idea to make a free MU account, this reduces the time you wait for dloads.
Select the MU link you wish to transfer. (It used to be a 200MB limit, but I have transferred over 350MB recently)
Wait for the MU counter to finish
Right click the regular download
select copy link location
Go to your RS account.
Select uploader from the bottom left of your screen.
Select Remote Uploads and paste your link.
Click add link. Then it's a matter of seconds (depending on the file size, server load) for the transfer.
This demo file I transferred (367MB) took less than 30 seconds.
