Many of the new oscillators are weak -- and designed down so as to appeal to the average homeowner -- especially the housewife.

I've had mine for about nine-years. I liked it better when I was the only electrician out there with one.
To restate the obvious, its place is doing things that no other tool can do: plunge cutting into studs is at the top of my list.
