I purchased a Humminbird 998C with a ram mount, navionics platinum, and interlink from http://www.jandhproducts.com
They have the best prices I found anywhere on all 4 items and were very nice and quick to respond to my emails. Be sure to email their customer service with the items you would like to purchase. I did so and got a good discount on the bird and a little off on some of the accessories.
Highly recommend these guys.
