Just a quick note to say that Waves are running a deal on these 2, they are pretty good at any price, but if you use FREE29 you'll get 2 for 1, I bouhgt them myself yesterday , tried them out on some keys, drums and bass... and they sound more than worth $14.5 (the list price is a crazy £500)
One is a compressor the other is an EQ.

Hope this helps
