If you're looking for a cool tool, a meg is fine if you use it.
But, another hip thing to have is a TDR!
(Time Domain Reflectometer)
I've had one for a while now, and find it very useful. Measures cable length, circuit in conduit, distance to open or short, finds hidden splices, and most have tone generators now.
http://www.megger.com/us/products/ProductDetailsBySubGroup.asp?ProductSubGroupCode=T101 I use it for general troubleshooting all the time now. Last time I pulled it out, I had a dead short in a really long circuit. Hooked it up, and it told me how many splices it went through, and how far away the short was. Count back 5 boxes, and 90', bingo!

Helps in find ing loose neutrals too!
