Best Deesser?

I've got the Fabfilter one which is regarded as the best but to be honest use volume envelopes to de-ess. Pensado says to look out for "little football things" at the start of phrases and pull the volume down on those.

SONAR Producer bundles two plugins with deessers, the VC-64 and VX-64 maybe one of those will work for you.

Another vote for the VX64 if your using all sonar plugs. Its quite good and can be tuned to the specific offending frequency. 

I'm having some success by first creating volume envelopes and lowering the offending passages, then adding a Sonitus multiband compressor set to lower the specific frequencies of the sibilance. But before I record any more vocals I need to read up on mic techniques for avoiding this plague.

I like this thread. Have a lead vocal that's not just doubled but tripled and it seems I have picked every word in the dictionary beginning with S and ive also sung it like a snake. I'm liking the volume envelope tip, am gonna try this first.

Sonnox Suppressr is my favorite de-esser, closely followed by FabFilter Pro-DS.
 
I have the Eiosis E2 as well and it's nice, but I don't think it's anywhere near the quality that the SOS review gave it (one of the reasons I bought it btw).  Now that Fabrice has joined the Steven Slate crew, he's apparently abandoned the plugin anyway and it's stuck in 32-bit land.  I've tried contacting him numerous times to see if I can sell it, but I've never gotten a reply (apparently, word-of-mouth says I'm stuck with it).

A zero-cost solution would be to get someone to punch your teeth out.
With that in mind, you could try different lip positioning on 's' sounds. Tightening the bottom lip can dampen the 's', but be careful not to sound short tongued. Widening the gap between your lips might also work. Maybe pulling the tongue back slightly would help.
Essentially, you are exploring mouth shapes that reduce the sibilance without affecting you tonal quality too much, and then training your muscles to repeat the action. My idea may work for some people and not for others. I only just tried it myself, but with practice it may be a good solution without spending cash on tech and banging your head over an EQ meter.
Of course, tight lips and growling teeth would look odd on a stage, but in a studio, who cares?
 
Anyway, give it a go. Let me know how you get on. Not punching youre teeth out of course.

One of the best de-essers ever is just using one band of a multiband compressor.  This is usually far more flexible than a de-esser.  You can precisely zero in on the offending frequency, you can tweak the threshold and gain reduction ratio, you can tweak the release.  You can also adjust the Q or bandwidth of the sibilance - how many de-essers give you that?
 
Basically, far more tweakable than a de-esser, but will out-perform virtually any purpose built de-esser ever made.
The Sonitus multiband compressor included with Sonar will do a stellar job.
