Simply the best! For a contractor you will use it more than you could possibly think. A lot of big box retaillers are not stocking this one any more, it is one of the few skill products worth a damn. The worm-drive is still durable, although they have cheapened it up over the years.  Buy extra blades, I have recently started using it for demo. sure beats getting beat up by the saw-z-all or sledge hammer, just have to figure a blade per job as "overhead".
