As the title says, looking for a good used gpx series. I regret ever selling my 4000 and 4500, and am looking for one as a backup. Age is no worries, as long as the control box is in good nick. Extras would be nice, but not essential. Must be willing to ship to Northern wa. Budget of about 3000, but will go higher if the right deal comes along. Not after anything flash, just a solid, well cared for detector. Cheers all.
