Having used it myself only recently, I can safely say that Audacity is horrible.
Well, it is a bit cheap, but it is the best program I could find that could generate tones ranging from sine wave to triangle. Audacity struck me as good because it was open source. I am trying to find a way I could give samples of what my projects sound like. Maybe I will host a few .wav or .mp3 files on my FTP server, so you all can find out if you like it or not. I just need to wait for some of my friends to come over and help out with this, I do not want it to be all one voice, it would be boring.
