If you like queueing downloads on a manager, type in:

javascript:alert(count=1)

Into your URL bar to get the download link without having to wait 45 seconds.
IMPORTANT: The link WON'T work for 45 seconds. You just get the address early.
This really is only helpful if you download in a certain manner.

On Megaupload Premium Link Generators: These are sites which don't actually give you a premium account. Rather, they own accounts.So they download it for you, and you download off their servers at a high speed. It's good for running downloads when you've already got one running. You can find them on google easily.
