AFAIK there is no such site. If there were a lot of people would have most likely posted about it by now. When I went to talk with a few stores on the look for my switch, they told me that they expected to be sold out of switches within the hour of their shipments. Loads of people are still looking for some, so the real question is are you willing to take a day off and stand in line. My choice would be to call every store when they opened and ask if they are getting their next shipment that day/week. If they say yes, and you really want a switch, you will stand in line.
