When Adafruit saw this breadboard-friendly module used in the Coobro Geo kit, Adafruit were excited to carry it as a separate product. It's a no-nonsense, high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built in antenna. The chipset is the latest MTK3329 which can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Of course the icing on the cake is the use of 6 x 0.1" spaced holes on the side which make it trivial to add to any breadboard or perf-board project.
The only thing you'll need to watch for is that the module is designed to run at about 3.3V, and shouldn't be powered by 5.0V. If you're using an Arduino, simply connect the GPS power pin to the 3.3V pin. If you want to configure the module, you'll want to put a 10K resistor divider on the RX pin so you don't put 5V on the data pin. Adafruit include these resistors, as well as a 6 pin header you can solder to the module in order to plug it into a breadboard.
Get started in a jiffy: after soldering together the module, follow Adafruit's wiring diagram to connect it to your Arduino or other microcontroller. Then run Adafruit's example sketch which will allow you to quickly set the update rate and select which NMEA sentences you want to have spit out.
