[aprssig] Garmin GPS-18-USB for $25 !

[Chuck Gooden]

Because they are different models of the GPS18.  Go to the Garmin 
website and download the manual and you will see that Argent is selling 
the LVC model which has a serial interface.  The other model is USB with 
the Garmin protocol.  Garmin has some software on their site that may be 
able to change the output protocol.  At least I believe that this works 
on the LVC model, not sure about the USB model
