I've got one of these, yes, very good sensitive GPS RX, and the Prolific 
drivers work great on Windows XP.  (Not tried on 'nix)

BUT...  Take care if you have Windows 7 (32 or 64 bit)  On this box, (32 
bit) the Prolific drivers (whatever version I can find) BSoD's the system 
after a random time when this device is used.  Irrespective of whatever 
application it's used with.  (Maps, APRS, GPSView etc.  Even PuTTY's 
serial terminal!)

Sometimes it'll work for hours, sometimes it'll fall over within minutes.

Windows logs always point to "Driver" issues, and the only "recently 
connected hardware" is that GPS puck.

Other Prolific USB<>RS232 hardware I have, is now stable with Win 7, 
after I got Windows configured to NOT to micro manage the USB subsystem 
power settings.

Take care.
