Think in terms of about 30 meters or so, on average, can be worse.
They are useless indoors.
I use mine for a ham radio application called APRS  (http://www.aprs.net) , as
well as for business travel. A moment to translate the address to GPS
coords, then just drive.
My normal mode is a 600-ish mile drive, and it brings me usually into the
parking lot.

<x-flowed>Specs are more like 50-100 m accuracy for run-of-the-mill units, at least
while the satellite signal is intentionally tainted by the gov.
Differential units that also listen to a ground station as a reference
signal get a bit better, but you aren't going to get accuracies of better
than several meters...certainly not feet or mm.

Depends on how long you occupy the station.  Surveying gps units do quite well,
but take a while about it.

YOu ought to get teh DeLorme software - you can skip the "put into GPS coords"
and just go to the street address.

My wife has used it to find faster routes from here to her mother's house.
