If you want to get in cheap, contact a Garmin distributor and tell them you want a GPS V refurb, they're selling for around $170 w/ the mapsource PC software ($100 addition to cost w/ most new units), 12v adapter, PC cable, and car dash mount, plus a certificate for one free upgrade on the S/W. If you wait to register the unit until you are ready for the S/W update you can upgrade to the latest version out. If you have a laptop you can interface with it while driving for location, the on-unit screen is B/W and not very big, but useable. hth
I wouldn't contact the cop, he sounds like a gay geocache stalker.
