Earle, I'd stay away from the Pharos GPS receivers which Microsoft used to include with the Streets & Trips software. They suffered from flimsy design. Holux 213 just like BU-353 are good performers, but if you can wait a few weeks, GlobalSat will start selling the BU-353 with a newer version chip, the SiRFstar IV. ETA for the new GlobalSat BU-353 S4 is March 2012.
