I bought this dewalt bisquit joiner to replace the old Porter Cable model (which was (is) the worse tool I've ever purchased).  This DeWalt is the exact opposite.  Simple to operate and produces quick and effective slots for the bisquits.  The only detractor I could mention is the dust collection system is prone to clogging due to a small chute between the blade chamber and the collection bag.  Additionally, I've had some trouble getting precise orientation of the slots when using the angle fence.  Otherwise this is one of my favorite tools.  Ranks even higher than my routers.  I'd buy it again in a second.
