1st, make sure if your on pc/laptop you're using firefox
then go here and get greasemonkey
then click this to install cavern links checker script which tells you if
download links are good or bad without leaving this site. (highlighted red link = bad/dead, green = good) this has saved me tons of time and guessing for a good download site

2nd, is FreeRapid Downloader. All you do is copy your link and this program will automatically download it, some sites require you to enter a captcha code and thats it. You can pause/resume downloads as you please.

**mod's sticky if you please
