Works and gets updated regularly.

Finally, a downloader that ACTUALLY WORKS!

Tried waaaaaay too many others that either didn't work at all...or worked for a month, then stopped working. SERP just works. Only downside: If you don't read instructions (like I did), you're going to have problems. But if you take 5 mins after getting it and watch the installation video, you'll save yourself an HOUR of frustration.
This is the one.
Oh BTW get the upgrade to get ALL the apps.. when you see how it works on one site, you'll want to use it everywhere.

Just an advertisement for the premium version.

Wow this is awesome!
