I have several Fluke Benchtop instruments. They are top quality. Fluke has been synonymous with Digital Multimeters for over 30 years. I have never had one of the pocket sized Fluke meters. But, they are overkill quality for this purpose. Additionally the low priced meters like we are talking about here have come very, very far in the last few years.
About a month ago I was looking for my meter on the Sears site and only found a $39.95 meter with duty cycle, so I'm pretty sure there's another one with duty cycle. Maybe they have that one in stock.
