Any recommendations for a noise reduction plugin for video post-production?

I'm working on a film right now and I'm looking for some alternatives to the stock Logic denoise plugin. Any suggestions? I've heard that the Waves W43 is good, but I'm looking for cheap (below $100) or possibly even free.

Voxengo redunoise. Very good and only 100$.
