I recently purchased one of the new Makita 16 5/16 inch saws (Makita Japan) and was very disturbed by the "feature" of a trigger lock button (locks saw ON) rather than the safety button that I'm accustomed to on older versions of this saw. Does anyone have any feedback on this? It seems to my that it flies in the face of common sense to have a lock on a saw this size. A replacement switch is available for an additional $35.00 plus S&H (~$6.00). The lock is apparently necessary when the saw is convertd to a table saw with an additional accessory (per the vendor). I'm curious if there have been any accidents attributed to a trigger lock on a saw like this. Thanks.
