This is great downod manager for mac. In my opinion better then iGetter. In past I used to be more iGetter oriented, but now I am Speed Download user. Best thing I like is drag and drop of text selection from text document to Speed Download window, Speed Download removes nonlinks text, extracts all the links and starts downloding them. Great stuff.
What could be bettar maybe are button icons (they are still ok). I would prefear they are more like Safari/Mail icons (hey don't blame me, I got used to that icons :-). But that said, I haven't seen any nice button icons that I like in any other non-Apple app (of any kind) I use so this is no big deal.
Anyway this is cool app and price is right. If you haven't tried it yet, try it now.

And don't forget they have nice MacBook worldwide promo going on this month!
