Also look at the more recent ones such as the APIs and the Master EQ. Sweet plug.

If I can recommend a plug it's the Mastering EQ, as Fleer said...what that thing does is
very nice...

Now...back to bashing IK...

Larry, we're counting on ya :)

I bought a bunch of them during last year group buy. There are very good if not the best. I like the EQ432 for mastering and eq81 for channel. Like the fairchild 670 and bus comp. If you don't mind waiting the group buy is at year end. Last year we all end up buying 5 for the price of one. I was really happy with it. 
I also have ST3 which I only paid $99 for during the intro upgrade price. I use ST3 mainly for playing back Standard MIDi  File. It is a great replacement for TTS1 in Sonar.
 

I like most of these, but a couple of them are HOGS! Linear phase EQ and British Channel have me tiptoeing around them. Linear Phase is toggled "off" by default ,which lends me to believe IK knows it's a system crasher.

Love IK plugs. Use them regularly.
