I must say 7-Zip is the current best. It's FREE, fast, straightforward, and handle a lot of types. It's also available in a Portable version; I carry it on my thumbdrive just in case.
PeaZip is cute and easy, probably better for the complete archive novice.
I just installed FARR (first time), and the file myaliases.alias is missing -- the MyCustom folder is empty. I'm actually an XML geek so copying and editing one of the permanent .alias files is easy for me, but I thought you would like to know about this behavior...
