If you're talking USB C to USB C, I'd check out the Choetech ones (I think that's the company name). My Google charger was damaged last week and I needed one urgently, I chose a new one from Amazon with great reviews for £7.99 and free one day delivery because I have a free prime trial. The lead has been brilliant so far (charges rapidly).

Edit: Found it on the American Amazon site: http://www.amazon.com/gp/aw/d/B017W2RWB8/ref=mp_s_a_1_1?qid=1460138452&sr=8-1&pi=SY200_QL40&keywords=Choetech+usb+c&dpPl=1&dpID=41Lf7I1TjwL&ref=plSrch
