while not really new, I have the stanley pro with a screen. Works 100% of the time on standard sheetrock walls. I don't like the magnet style at all, as you have to search a bigger area, which takes more time. It definitely works better than the 12$ cheap ones with 4 lights.

I also like the electric wire finder light--it makes me especially careful in those zones.

No doubt their are better ones out there now, but this one gets the job done.
