I have this one, but it was only $80 last year. Works great but doesn't support auto power off so it kept connecting and dropping off as I walked around inside the house. It would probably cause battery drain if it sat long enough as well.

I did order that setup with the usb splitter and power blocker so I won't need to flip the switch.
