Need a midpole Snuffer...HELP PLEASE!

I am looking for a midpole snuffer....Needs to be large for a H21SE so the chutes are 35 M^2 and 25M^2
Check out SNU snuffers: http://www.gobarefootstudio.com/snu_08.html
Thanks Dan, I have come across that before. I saw someone sell a snuffer used on here for $150 and was mad I missed it.
Dito on the SNU_SNUFFER. Got one for my Hobie 18 and love it. Als got a cover with it for protection.
I made one from a tennis racket head and some fiberglass, sock material from sailrite. Dirt cheap but much more work than I expected.
