the whole waves collection means everything to me. i just couldn't work without them. it's the essential collection bar none.

then the ableton plugins - my god how easy and quick are they to use??

then i'd be screwed without:

tc native bundle (purely for the side chain comp for both my mac and pc)
camel audio crusher/phat (i would die without these)
arts acoustic reverb (no other verb comes close imho)

all other plugs are toys :)
