Where can I get the best deal on a Lowrance HDS-7 Gen2 Touch? I will be getting the options for down and side imaging, and chartplotting. I'm not sure what transducer to get yet though.

I also currently have a HDS5x, but I'm not sure if it will interface with the HDS-7 or not. If not, no big deal. It will get mounted up at the bow on the ipilot anyways most likely.

Any help?
