Thanks guys.
I have the handbook on CD for the 2005 cycle.
I like it but before I bought again, I just wanted to make sure that I've looked at my options.
I signed up for the one-day trial of the NEC plus. It seems pretty good. I especially like how quickly it links to other pertinent info (UL white book, illustrations, staff notes...), and having access to 70E is helpful too.
I'm still not decided which way I'll go.
