Dick smith has most of the wemo range on sale. Bunnings now stocks these so you can price match for an extra 10% off.
The Belkin app kinda sucks but the hardware is good. I recommend the 3rd party app for android called wemomanager it has tasker integration so its really powerful.
If you just want wifi controllable power sockets the wemo's are good but I recommend checking about the broadlink SP2 on aliexpress. They are a bit cheaper and I reckon they are just as good as the wemo's. They also have tasker integration with a 3rd party app. I have tried a lot of this kinda thing over the last 3-4 months and I think the broadlink and wemo stuff is the best.
If you're an iOS user, hold off on buying gear like this until it supports HomeKit. I fitted out the house with Philips Hue bulbs and now I have to buy a new hub. If you're not fussed, buy all the old technology cheap!
