At the Kansas City Wood Show this weekend, the Bosch dealer demonstrated the REAXX saw using a German sausage. It detonates what looks like a pellet gun cartridge. The cartridge costs about $50 a piece and the system resets in about ninety seconds. It should arrive shipped to the house around June 1. I wanted a REAXX since some of the folks who help around with carpentry aren't the safest around tools.
