I had a Dremel oscillating tool. It worked ok but you needed to use a hex (Allen) wrench to change the blades.
Then my van got broken into and one of the items they took was the Dremel. For a replacement I got a Porter-Cable.
It has a quick release so changing the blades doesn't require any tools.
Most all the brands of blades fit so I have a wide choice.
I went with the corded model.
I almost want to thank the punk that ripped off the Dremel. That's how much better I like the Porter-Cable.
I'm good with the Sawzall but the oscillating tool allows me to make detailed cuts that would have taken a long time to do with any other tool.
There are metal cutting blades that should work well for wire mesh.
