Non-shelving de-esser? Free?

[Reggie]

Hey folks, another de-esser thread here. Does anyone know of a decent non-shelving VST de-esser? The two I have found (spitfish and mda) shelve down the high end, rather than notching out the frequency. Or perhaps a flexible multiband compressor that works pretty good for something like this? The free multibands I have found don't allow a narrow enough band for what I need.

Thanks
