Funny that Garmin 182 came up...I just helped my neighbor get a 182C (color) and a region 23 chip from Cyber-marine.com.
He talked to all the local retailers and $999 was the quote. Cyber-marine.com (where I bought my map76) quoted $885. I think I talked to Rob over the phone and he seems very knowledgeable and a straight-shooter.
$115 saved plus taxes.
