It had crossed my mind that some of the advertised units may be stolen.
There is no such thing as a free lunch. I've seen 430's advertised as low as US$2500, they must be either shonky or inoperable?
Quite a few of the ads say email me for the serial number of the unit for sale.
I wonder if Garmin would have a database of stolen units that could be checked.
I might email Garmin and ask about their views on second hand units.
