Summary: I returned two Black and Decker jig saws because the blade was being held at the wrong front-to-back angle and bought this at about twice the price. It uses a screw to lock the blade in place, but it's lighter, much quieter and with far less vibration than the Black and Decker saws -- fare more comfortable to us than the Black and Decker model I had. It also comes with its own tough plastic storage/travel case, but it stinks of plastic chemicals -- keep it closed.
Summary: I wish I had this saw for the last 25 years. And I'm glad my low quality old saw burned up. Very high quality. Used it to trim joist boards on my new deck and it performs perfectly. Saws easy and straight and very low vibration. Worth every dime I paid for it. Would be nice if it had a light but not worth the extra bucks in my opinion to buy a higher priced model with that feature.
Summary: I've owned a number of jigsaws in this price range and none satisfied me the way this Makita does. I decided to try the Makita because I have two, "ancient", battery powered Makita drills and a Makita battery powered jigsaw and they have never let me down. I dropped one of the drills from a six foot ladder onto concrete yesterday for the up-teenth time and no problem. The most notable difference I've experienced with this saw is its smoothness. Vibration is notably less.
