Which brings us back to a Garmin off ebay!
It wouldn't be my first option either, but as Pol had suggested it might be feasible and having come to the "garmin handheld" conclusion 3 years ago, I thought I would throw my findings into the pot. There was a USB dongle that talked NMEA, but like the NMEA antennae, Maxhar would likely be as cheap buying a handheld which would then give extra functionality and could be used for hiking / biking as well.
