Just wanted to let you all know that I just purchased a GlobalSat Bluetooth GPS receiver from www.semsons.com and it is GREAT! It comes with both an AC charger and 12V DC car adapter. Set up was relatively simple as well. I actually use it with Maptech software for Colorado, providing me with location on USGS Topo maps - handy for mountains and Jeep trails. I hightly recommend this product. It has a rechargeable battery (with a supposed life of 8 hours, though I have not tested to see). Of course, there are several other models to choose from. Check out the forums at www.gpspassions.com - they even have a Bluetooth GPS receiver shoot-out.
