I just thought I'd add this minor point here instead of in a new topic: in the Unrar settings, the 'Create subfolder based on NZB name' works basically the same as 'Create subfolder based on download folder name', and therefore is equivalent to AutoUnpack's very handy 'Reconstruct source folder at destination' option.
Also, manually entering the download folder name, either when adding to the queue or after, is equivalent to Newsleecher's 'Leech - Specify' option, etc.
Flagging up these kinds of equivalencies somewhere might help to make the transition to altbinz a bit easier for some folks.
