Mine arrived today. I have never seen such a fast Cold Start. Works fine
with all my applications and is sitting in the living room with 12
satellites locked!

fine with APRSIS32, Precision Mapping S&  T, and my dumb terminal program.
UI-VIEW32 sees the port, and complains when the GPS is not plugged in.
However, it does not appear to be seeing the data.  Show GPS Input just
shows a blank screen.  $GPRMC data is present and valid when I look with
another program.

I received my USD $25 Globalsat BU-353  USB GPS today.    Within 3 minutes
of 
delivery, I had it plugged into a USB port on my Panasonic CF-51 Toughbook
(15" 
CoreDuo 1.6 GHz laptop), and working perfectly with  Visual GPS, MapPoint, 
UIview, TopoUSA 8.0   --AND-- Precision Mapping 9.0.   All simultaneously
via 
the freeware XPort GPS port splitter.     Get this extremely useful GPS
utility 
here:

. <http://www.curioustech.net/xport.html>

As soon as I plugged the BR-353 in, the existing Prolific driver on my
system (used with several other USB GPSes and Argent Data's generic
serial<-->USB 
dongle) immediately enabled it.   One reboot, and it acquired lock in about
1 
minute positioned by a BASEMENT window under an overcast Michigan winter
sky.

Normally, I have XPort intercept the physical COM 1 port on the Toughbook
(that I use for a serial GPS) and output virtual COM4 through COM12 which I
use with the various apps. All I had to do was change XPort's INPUT port
from COM1 to the virtual COM16 created by the Prolific driver to get
everything to work with the USB Globalsat instead.  No changes to any of the
apps required at all.

The unit is very small, lightweight but nicely finished, with a beveled
round case that looks like a tiny flying saucer about 2 inches (5 cm)
diameter.  
Should be fairly aerodynamic at high speeds mounted to the roof of a
vehicle. 
The magnet embedded in the underside is powerful enough to stick to a
textured vertical surface such as a refrigerator without slipping.

Interestingly, the plastic case does NOT have the usual sonic-welded
closure.  
It is actually held together with 3 tiny Phillips-head screws, so opening &
hacking the device (serial output???) non-destructively should be possible.

A single small low-intensity red LED (thank god not one of those
screamingly-bright blue LEDs currently fashionable on digital gadgets!)
lights solidly during acquisition (verifies USB power)  and starts flashing
when lock 
is achieved (like the GPS legend on the Kenwood D700 screen).    This
indicator 
will NOT be a blinding distraction on top of a car's dash at night.

I have run it with both the Panasonic Toughbook and an Acer ZG5 netbook 
successfully.   This gadget is definitely an excellent value.
