Wattvision (YC W09) Power Monitor: Best Price through Energy Circle

I'd love to buy this thing, but at that price, I can't justify the expense. $49 seems like the sweet spot for me.

As a card-carrying member of the fan club I find this quite a treat. Go Wattvision! A monitor on every meter!

I love this gadget - we are trying to invest in energy efficiency (as a business - we pay upfront for efficiency improvements and collect a percentage of savings) and this could be a great way to reduce the cost of ongoing monitoring.
