Just wanted to say I got this Holux 240 receiver, its the size of a stick of gum, weighs next to nothing, 8 hr battery life and SirfIII level so its quick on the satellites and keeps them. Using it on my Sprint Treo 700P, and it works like a charm. Just had to put in a good word and say everyone should have this thing if you want a portable GPS unit, or start geocaching outdoors, hiking, biking, boating, or walking the city streets or, even be followed by Big Brother (tinfoil hat not included). Go get one now!! Cheapest (80 bucks plus shipping) is where I got it at, in 1st link, second link is just one of the reviews out there that shows some good comparison pictures. Any questions , message me! I'm no sponsor or anything, just a customer of a great product and I am really enthused about it and want to spread the word. http://www.buygpsnow.com/ProductInfo.aspx?productid=616 http://www.waterman.ca/240%20size.jpg Wanna kill these ads?
