I'm cheap enough that I haven't upgraded to the new Sawzall with tooless blade changes.
Call me old-fashioned if you like, but I often prefer the traditional fixings.
I had two Makita jigsaws, 110 and 240V versions, one with "Quick change" the other without, but the same model in all other respects. I found the blades easier to change on the old-style clamp with hex wrench than on the one with its "Quick-Change" mechanism on the top.
