I picked up a conventional rotating eddy current rotor utility power meter at a junk yard, and it's really quite accurate ( Public service laws require a certain precision since you're being charged for the power). ( The number Kh stamped on the label is watt hours/revolution ). I recently bought a fully digital power meter from Newegg.com for US$17 :

I haven't tried it with pathologically shaped waveforms, though. Yes -- a $20,000 scope would be better :-) . My guess is it's using the new ICs designed for the electronic versions of smart utility meters.
