If you are still shopping for the motor, charger etc, you wont find any cheaper pricing than from BBG Marine. Give Brian a call. He is required to advertise list price on his website, but he discounts (almost) everything. You just need to call him or email him to get a quote.
I have purchased two different Minn Kota motors, three battery chargers, my old Humminbird sonar system, my marine radio, and my complete Garmin system and just bought the new LiveScope system from him. Ive probably spent $10k with him over the last several years.
I check prices all over the net each time and he is always the lowest - and not just by a dollar or two. Even including shipping from back east, the Ulterra we bought was $200 cheaper than anywhere else. The new Livescope was $100 less, etc.
He carries everything from chargers, to plugs, and cables, to motors, radios, sonar etc.

Remember, you have to call or email to get the real pricing.
Other than that, I highly recommend the Ulterra with Bluetooth if its in your budget. The spot lock is sooooooooo much better than anything else out there. Its awesome to be able to hold the boat inside a 5 ft circle instead of a 40 ft circle when you use spot lock. I will never own another trolling motor that doesnt have that feature.
Good luck with the install! I think its an easy job, but I have experience with electronics etc. I highly recommend the quick disconnect plate. Aside from a good idea if you use the motor in salt, its handy other times to be able to quickly remove the motor.
