1. Humminbird 898c si. Bought a new transducer this year (185$). Also comes with external GPS antenna as well as an extra mounting bracket. I had it on my small boat and it worked great. Lackskill just updated his electronics and gave me a Helix 7si. that's the only reason I'm replacing. Just check eBay to see what they were selling for. The cheapest one this year sold for $290 and didn't have the external GPS puck.
2. Humminbird 153. Works great.
There located in Brighton.
