A set of free plug-ins. I have only tried the MCompressor, but it looks to be a killer contender for the Classic Compressor. I prefer Classic's ease of use, and I like the 'warmth' it adds, but I needed something more transparent for a rhythm guitar track I was mixing, and MCompressor seems to handle that well.
