I've bought a Chrome cast a while ago and was looking for a way to connect it to my basic TV which has only 1 HDMI port along with my PS3. This is a cheap yet not a bad solution. The best thing about these HDMI ports are the auto detection feature. For example when the PS3 is off, it is automatically casting the Chrome device and when you turn on the PS3 it switches back to that and when you turn it off it will cast on Chrome again. THere is also a button on it for if it failed to switch automatically.
I've tried to post an ebay version of this earlier, but it was removed by HUKD, however you can get it cheaper on ebay for £1.88 (which I did myself and received it within 10 days). I will put a link off ebay too and decision is yours which one to choose from.
