Gear bought from eBay.
I finally jumped on the Google Home bandwagon. I skipped it last year at US$99 due to an immature ecosystem, but six months on it's improved, now supporting Logitech Harmony, iRobot, Sensibo, and more, with more accurate speech recognition.
I found this really cheap external battery charger for the iPhone 3G via HardwareZone forums. The seller, free-4-flying in Hong Kong, runs occasional sales; I've seen it as low as US$6.99, though I paid US$8.48, around S$11.87 including shipping.
