To be clear:
Black & Decker has OWNED DeWalt since 1960. Stanley and Black & Decker merged in 2009. DeWalt is Subsidiary, as is Porter-Cable (since 2004).
While DeWalt has certainly had some problematic models, their tools are professional quality and much different than the B&D line of products.
There is no question that Festool makes quality products. Howver, at 5x the cost, they better be good tools!
