OBDLink introduced their EX model recently. It is a corded OBD interface specifically for Forscan with automatic dual CAN bus speed switching. Beats remembering to flip a switch on the other maker's interfaces.
Amazon had them for $33 at black friday time, seems they are $49 now. It has a usb interface, not bluetooth or wifi, so it is a more reliable connection, albeit you are still tethered to the vehicle.
Thats a lot of money compared to other obd interfaces, but OBDLink tends to make some good products which are supported with regular firmware updates. I have the EX, the LX and the MX+. The MX+ was working fine for me, but when I would switch to a different laptop, it took some finagling to get it communicating with the laptop's bluetooth drivers. The EX did not have this problem, actually, just plug it in. If it wasn't recognized, unplug and then plug in a second time. Then and there after it was recognized.
Oh, EX is only for laptops because of the USB connection.
