welll.. it's uhm.. *cough* certainly inexpensive. :)  Honeslty though, you would have to read reviews of folks who have used it. The trick will be getting it to trigger properly and I have no clue if it has a good trigger circuit on it or not.. and if it can capture just a single trace or if it would continuously trigger etc etc.. and the real cost will be the current proble since that is what will let you calculate the power being used by the device.

Generally speaking, power measurements are something that takes a fair amount of not cheap equipment to get. It lets you do things like find inrush currents and operrating currents curing various useages.

If you are working on at a hobbyist level, then you might be able to simply use teh data sheets for the wifi device and simply use max rated power consumption to estimate your overall power needs. If this is for an actual product development for a client, I would suggest asking the client if they have that kind of equipment available or know of someone who has it available so that you can get "proper" power measurements. 

I would suspect trying to get that information on the cheap will be a frustrating excersise at best, and generating misleading results or impossible at worst.

Unfortunately I don't have access to an oscilloscope though I have been seriously considering buying the little one on seeedstudio.com <http://www.seeedstudio.com/depot/digital-storage-oscilloscope-diy-kit-with-panels-p-166.html>. If you or anyone else has an opinion of that device I would be interested to hear it.
