$50K is not a serious amount of money to help influence the CPSC or legislation. That only gets you a few phone calls/emails and attendance at a few committee meetings when an issue comes up that may impact your interests. The Power Tool Institute has spent a whole lot more

through the last 4 years and has successfully stalled any action on this subject until now.
I look at this simply and am optimistic a reasonable solution will be found. If you are concerned about the cost please consider that the only solution right now is made in the US and is attached to Cadillac quality saws while ~90% of the Tablesaws sold here are made in China. Earlier a post was made about the large number of Patent applications related to this. Whatever happens will add a small additional cost to a tablesaw and not destroy it. Once this becomes standard I doubt anyone will want a tablesaw without it. Would you buy a car without seatbelts and an airbag to save a thousand dollars if you had the option? I wouldn't and I obey all the safety rules. Doo-Doo happens to too many careful, experienced and "reasonable" tablesaw users for this to be ignored.
