I like MP3 DirectCut for what it does. I have also found and been using WavePad. When initially downloaded you will get the full version. If you decide not to buy the full version, it will block some of the more advanced features. You will still be able to use cut/paste, EQ, Amplify, Trim and a number of other features.

It's worth a look and a little experimentation at no cost.
