Comment on RarMachine

Just a FYI before purchase of this application:

It should be noted, that you will need to buy a separate RAR license (of which the copyright belongs to Alexander Roshal), if you wish to archive files using this program (or any other program using the RAR compression scheme).

Further info on how to acquire a RAR license (currently priced at $29) can be found here:

As of this writing, the current OS X version of RAR is RAR for Mac OS X 3.80 (direct download link).
