I am learning so much from the forum. I wanted to know about extension cords and then came to know that I will also need adapters from say NEMA 14-30 to NEMA 14-50 which can be added at one end of the cord and then this can go in dryer plug. So far only place where I am seeing adapters is http://evseadapters.com/adapters-for-tesla-model-s.php This looks like a good site. However cost starts from $55. If we buy few types of adapters, I am seeing spending ~$150 for adapters and then $104 for the cord at Amazon. Just wanted to know if folks are able to find adapters cheaper else where. If yes where?
