Buy.com, the part number they list is the old BT100, not that it's 100% guaranteed. Thanks for the tip on the a7. I have looked at the host-XR, it peaked my interest but was hoping to spend less. Probably need to do some more reading before I pull the trigger on anything.
I have not done the modification to add the external connector yet, but I have been looking to buy another BT100 to do such a thing.
Although I have not had much luck with the BT Exploits I have tried in the lab, so might give up on this until more support is available.
