FFmpeg. As you can see in this list it supports quite a number of formats. The command-line tool is difficult to use if you're not comfortable working with a command-line interface.

I've got the trial version of Goldwave (as far as I know, the same as the retail one, but with a useage limit). I also personally found a way to make that trial last... quite a long time.
