We write fleet management and tracking software, so have tested many units. The cost is coming down, both for hardware and the GPRS data transfer costs. The cheapest packages out there at the moment cost around £400 over a three year period (includes hardware, data transfer, software etc). Compared to a cheap GPS data logger, this will look expensive! But for businesses who want to improve efficiency, save fuel, help logistics etc., it is certainly worth it.
Even the fastest trackers can only send data every 3 seconds, Any faster and an intermittent GPRS signal can cause a backlog, which falls short of the every 1 second suggested for osm data. Even then the data sent often does not have all the meta data attached (e.g. HDOP etc) which a gpx file or other formats may have and could potentially be useful to osm.
