De-essing

does anyone know of any de-esser sonar 7 producer edition offers besides the vintage 64? if not, what about a free download for one?

Spitfish works quite well as long as the track is hot enough to fall within its detection range.

You can also use the Sonitus multiband compressor in a pinch.

But far and away the best method, especially if you're dealing with a particularly nasty sibilant track, is the old-fashioned way: clone the track, brutally EQ the clone so it's all in the 6-8KHz range and compress the hell out of it. Then use that mutilated copy to drive the sidechain input of a compressor on the vocal bus. You can use the Sonitus compressor for this.

haha never mind. forgot its a vst plugin

You can do that. But there isn't much above 8k that's going to be a problem. Sibilance normally lives around 7Khz, give or take depending on the singer. What you want to do is emphasize the nastiest, screechiest, teeth-gritting-est parts. When it hurts your ears to listen to it, you're there.
