Fluke meters are the best that I've found.
I'd warn against using any of the cheapo, Harbor Freight style multi-meters. I read an article about an electrician that was using a cheap multimeter on a 277/480 volt panel and the meter failed, causing a phase to phase fault and arc blast. I can't recall if it was fatal or serious injuries, but not a good situation. The meter was supposed rated for the voltage he was using it at.
