I just got a refurb from Johnson Hicks Marine in Santa Cruz. They had it listed on Ebay for a $479 starting price. I called their office just to ask about Garmin warranty on the refurb and he offered to sell one to me over the phone for that price. I snapped it up!! He still had a few more as well.
Later that day, the ebay listing sold for $676.
$479 shipped, with all the goodies and Garmin warranty. Even got a free map upgrade when I registered it. I'm very happy with that.
