West Marine had a pretty good deal on a open package Lowrance H2OC a few weeks back. I have the same handheld and it is better than any Garmin I've ever owned(3), and much cheaper for the same features.
There was a Garmin 76 in the Sunday Democrat in the < $100 section. If I remember it was either $86 or $89. Add said it was like new. Probably gone by now.
