Thanks much for the warm welcome everyone and
big thanks to MiseEnPlace and chefboyrdavid. I edited the MP3 by converting it to a WAV using Windows Media Encoder (free download from Microsoft) then trimmed the sections using Windows Sound Recorder (comes with standard Windows). Got just what I needed.
I set it for my home custom tone and called my cell from my home phone. Boy was my GF surprised to hear that.
Thanks again everyone!!
