Take a look at the matrix series by Humminbird.  Their Matrix 12 is about $150.  I had an older Matrix and it seemed to work pretty well.  Just a thought but, for a buck fifty you probably won't get a color one unless you go used.  As far as the suction cup mounts go, I would just get another transducer to mount in the other boat.  None of the FF are going to come with a suction cup mount so you will have to buy it seperately and they are the same price as a fixed mount one.
