.rar files on a Mac?

On windows i'm used to WinRar... but what's the best Rar Archive program for the Mac?

i just got a home made video from my cousins wedding, and he rar'ed it into 45 files... i need to put them all together now back as one file!

The free Stuffit Expander will do this.

I also like MacPAR Deluxe (shareware). There are other free or cheap unRAR utilities, check MacUpdate.com and do a search on RAR.

UnRARX is free and will extract RARs. If you want something more full-featured like WinRAR, check out BetterZip, which is shareware, but fairly inexpensive.

BetterZip is "better" for handling 28 archive file types.
