Cool Tools compares two small GPS data loggers, the $190 TrackStick II and the $70 iBlue 747, and finds the cheaper iBlue model superior in almost every respect: more memory (16 MB vs. 1 MB, for up to 100,000 logged points), more GPS satellite channels (32 vs. 12), and options for use (Bluetooth GPS antenna, USB GPS antenna and stand-alone data logger vs. no Bluetooth). The 747 model uses rechargeable lithium batteries; if battery life is an issue, iBlue makes the iBlue 757 model, powered both by batteries and a solar panel, for only $5 more (slightly larger, and only 8 MB of memory). Standard NMEA serial output through a USB bridge if you’re using it as a GPS antenna hooked up to a laptop; logged data can be downloaded in CSV, NMEA or KML format (you can convert this data to GPX format if that’s what you need).
