After making up my mind to get rid of the old B&D jig saw, I decided to move up to a professional grade saw.  Read up on the Freud and like the features and price.  Have use it a few times and I am impressed with the cutting power.  Putting a blade in with the quick changer went smoothly.  I bought Bosch blades for it and I'm sure they help take advandage of the Freud's power, cuts very quick.  Some vibration to it and the noise level is not too bad.  All in all, it's a beast.  I like it.
