You want good customer service? You can't beat Humminbird. Easy to update the software, easy to install maps (just plug it in!), more user friendly. Good quality units. Check into used units too. Check here first of course. Don't buy from anyone with a couple posts. Do your research and buyer beware. That said, I have bought a HB 1197, and a HB 1198 NIB private sale online with no problems. I saved $1000 on one unit, $700 on the other.
