M-241.: Holux M-241 Bluetooth Data Logger GPS (Runs on AA Battery, MTK Chipset, 130,000 Waypoints)
I needed a GPS Logger with bluetooth compatibility for Foolography Unleashed GPS receiver. M-241 matched perfectly the need and I'm able to see GPS coordinates in my photos.  Pairing Foolography unleashed was little difficult but after 4-5 attempts I was successful. Once paired, this duo worked seamlessly whenever turned on.
