I have a Humminbird 300 that I got at Sportco for all of $119. Has all those features and also has sidescan sonar - sees fish out 45 degrees to each side which is way cool for fishing in shallow water like the CR, Willapa, GH, etc. This thing has stood up to 3 years of heavy abuse now, including regular smashing of the transducer on lousy boat launches, and still works great. I figure with the way I break things why go for the big ticket item like the Garmin when I can get 3 or 4 of these for that price
