I always ignored those hofa plugins but i will give them a look now

+1 for Cableguys Pancake2. 
 
Also add Voxengo Boogex.
 

When did Voxengo Boogex go 64bit? Better still where is it? http://www.voxengo.com/product/boogex/ only shows a 32bit version.

bitfliiper, scook beat me to it.  I was trying to find 64 bit freebies since more and more people seem to be trying to streamline their plugins to 64-bit only.  There are tons of great 32-bit freebies  that will work via bitbridge and j-bridgebut I figured limiting it would provide a more concise list of things people actually use instead of merely collect. Boogex was awesome though!

That pancake2 plugin is insane and a keepere
 

Sorry, I thought Aleksey had made everything 64-bit by now. You're right: Boogex would appear to be abandonware.
