I saw this on the Volt and Leaf forums and subsequently ordered 1 to replace a damaged factory charger, but with a L2 end on it:
http://www.e-zencar.net/ - they sell the 16A 220V (third pic down) for about half of what you find online at Amazon or Ebay. You will have to request a quote. Amy is their customer service person and was very good about my order- you have to pick your cable lengths and what type of end you want on it. They make it to your specifications. I ordered 6 meter long J1772 end and 1 meter long plug end.
I actually ordered 2 and they cost about $150 each, but I sold one on Ebay for about a $200 net return (after all their fees). So about $50 and its been working flawlessly since February.
It might be good to mount it in a lockable electrical box... but mine has been outside the entire time with no issues.
