I found a great program called wavepad. it is very user friendly. it lets you take any song, or other audio file, and you can edit that song. you can choose where to start the begging of the ringtone and how long you want it and then you just save it as m4a and convert it to m4r. also you can make the actual file louder so that you have loud ringtones that you can actually hear lol. its not designed as a ringtone maker but i found that it works perfectly and best of all its FREE!
