I tend to agree with Packard and I'm not a casual Sawzall user, over the years I've owned 8-10 different Milwaukee Sawzalls. Currently, I keep a cordless in the garage and a cordless & corded down in the shop, they're used for everything.
There have been times however, like when cutting into a plaster wall or drywall ceiling that ANY form of dust collection would have been a huge game changer and that dust attachment would be a worthwhile expenditure.
I can also see that it would be nice if you were removing old windows and needed to cut the window frame in several places. But for general renovation...not so much.
My largest concern is how smooth is this new Festool/Flex saw and how robust is the reciprocating mechanism. I remember 25+ years ago when Dewalt decided to first enter the Sawzall market, the plethora of issues the construction community had with the new Dewalt offering. Once the metal or wood item was cut partially through and the blade was pinched, the reciprocating mechanism destroyed itself within seconds/minutes.
Milwaukee has been making these things since 1953 so there's 70 years of history here.
