Hi guys I've been toying with the idea of getting one of those little hand-held GPS units. The ones that are WAAS/EGNOS enabled. How accurate are they in a real life situation? They claim within 5 feet, but life has made me somewhat cynical about manufacturer data! Lets assume that we have a decent number of satellites. And I have good reasons for needing that kind of accuracy! America has always been ahead of Europe when it comes to these sort of gadgets and I look forward to your opinions.
