Is there a cheaper version?

Of all the things that I dislike doing the biggest pain is the time it takes to go through a vocal track trying to make all the regions sound at or about the same level! I have just become aware of a wave plug in that does this automatically. The Waves vocal rider. It looks like a must have but it appears to be bundled and the cost is way too much for me. I don't know if there is an equivalent that is available as a stand alone in rtas format but if anyone knows please enlighten me. Thanks.
